Installation had no problems here (although I do have 2 firmware update tools in the start menu)

Projects opening perfectly too :)


cant hardly wait to start. :)


Install went fine. But when I try to open a project, I get "Unable to load C:\Users\jdeba_000\Documents\EZ-Builder\MyProjects\gb-wbwithoutcam.EZB. Reason: There was an error reflecting type 'EZ_Builder.Config.ConfigurationV2'

I am going to uninstall and download again, And try again.


Uninstalled and download again. Installed okay. But same error. Using Windows 8.1. J

made new project it works, but unable to save get error "Unable to save C:\Users\jdeba_000\Documents\EZ-Builder\MyProjects\gb.EZB. Reason: There was an error reflecting type 'EZ_Builder.Config.ConfigurationV2' j


Same problem as jdebay, can't open user projects including sample projects or scripts... Also can't open anything from EZCloud.....


Same issue: Unable to open projects (locally saved or cloud)


Can you check and see if there is a previous version installed still? Uninstall all ARCs, reboot, and install this one.


There was a previous version installed as well as this new version. Deleted both versions, re-booted, installed latest version again ,same issue. - using Win 7 -


found two versions also. uninstalled both. clean register. shutdown. restart, install, same problems. stress stress stress stress j


Interesting... There is a cached file somewhere on your computer from the old version. Can you uninstall, then check the C:\Program Files(86) folder for an EZ-Robot folder?

If there is one, can you tell me what is in it?

After you screenshot or save what's in it, delete it. Then install the latest version


Did the same as jdebay and also have the same problem... Uninstalled all versions of ARC, re-started the computer and put a clean install of the new version of ARC... Still no worky... :(


Do you all have Windows 7 or Windows 8?

The trouble seems to be with the new installer for Visual Studio. They got rid of the old Setup and Deploy feature and replaced it with Install Shield. I spent nearly 8 hours yesterday evening trying to configure Install Shield. It is very buggy and kept losing my settings. The installer works on my computers for testing, we'll have to narrow down why it's giving you guys grief


After removing all versions of ARC... what's left in C:\Program Files(86) folder is a folder(s) named \EZ-Robot Inc\Ez-builder\media... Nothing is in the media folder

United Kingdom

Just to add (if it's of any use to anyone);

Windows 7 64bit Downloaded and installed new version last night without uninstalling the old version Works fine, opens any project I have tried locally and on the cloud.

Control Panel --> Programs and Features does show 2 versions installed but nothing is causing any problems.

Contents of my %Program Files (x86)% directory are; User-inserted image

Edit: Also, this is what I have installed... User-inserted image

Also, I have UAC turned off completely. I mention this as someone posted last night about not being able to install as they were not admin. A long shot but it may be related.


My Win 7 Pro does not have the x86 program files selection, only program files. After uninstalling both EZ-B folders and a reboot there is no reference to EZ-B folders within Program files. Downloading the latest version still results in the same error.


@Robot-Doc question do you have ms office 2010 installed? @DJ question no ms office?



jdebay I have a license for MS Office 2003 and that's what is installed on this machine, Win-7 32 bit. Also installed Windows update for .net 4.5.1


@Robot-Doc the reason I asked was I have ms visual studio 10. installed. And I think that installed with office 2010. j


I do have Visual Studio 2012 installed as well as VS 2012 Express.


@DJ Sures... It is installing, I just can not read current projects. I can make a new project and test it, but unable to save it. I have ms visual 10 install. I notice @Rich does not and all is fine with him. I can send install.log if that will help? j


The installer is not installing the dependency files. I have isolated the issue - now I need to resolve it.

I'm confused of why Microsoft would have removed the Setup and Deployment feature from Visual Studio 2013. Install Shield is really buggy, bloated and has a confusing setup process. After doing some google searches, it seems there are countless number of people who are upset at Microsoft for removing that feature...

We will get through this guys! :D


@DJ Sures that is great news. I am here to install the latest, you are the man.



I have always (back as far as vb5) preferred MS Deployment over Installshield even when I had access to an enterprise license of Installshield. The MS tool was simple and effective. Tbe only Installshield feature I thought had any value was the ability to have it pull missing components from a local or Internet server rather than including them in my distribution package, so my packages could be smaller. But, that required Internet acess during the installation and caused problems for some of my enterprise customers, so I wound up always including the components anyway.



Cannot load my robot file after update? I never had to agree to license before an update? I am not sure how to go back to previous version that worked on my windows 8.1 before? Can someone tell me how? I shut down, but no ARC. I had a big long error message that I could not paste here. Are things getting too complicated? I do not have MS Offiice on this PC. ARC needs a recovery option. Steve S

@Steve, ARC generally works fine after an update however in this instance, as pointed out, it is very much a beta. A "recovery mode" would be pointless to be honest.

ARC is, as always, evolving. If you have a robot that works and you are happy with it and don't plan to make any changes or updates to it then don't update the software.

If you want to roll back to the last version start by uninstalling the current one Download this version and run it.


Thank You so much Rich, You offer great help! I will try it. I wanted to do the update to take advantage of faster response mentioned in the release notes. Steve S


Steve, the update notes mention a warning that this version may cause issues. We're using the community to resolve the issues. You have no volunteered to help :)

I'm still actively working on a solution to find out why Install Shield won't work.

I have the merge modules all unselected, but it keeps attempting to include 64 bit merge modules even though they are all unselected. I select the 32 bit merge modules but Install Shield continues to force the 64 bit modules.

Also another bug with Install Shield is the "File Extension" is not saving the selected application.

I'm having a hard time believing that there is a world of people using Install Shield with all of these bugs i'm experiencing... mad


Now it keeps crashing when I try to change settings...

User-inserted image

Haha, it's not all fun and games building robots! When you're at the mercy of a company who doesn't make a reliable product...


So wait. do you need VB installed? I have vb 2012. Does this change anything about installing?


No you don't need VB installed.

This has to do with 64 bit merge modules being installed for a 32 bit application. Some of you may have the correct 32 bit merge modules from the previous installation - or another software program.


Sorry DJ, I should have checked the latest release notes, just opened ARC and chose update. Thought I was downloading 12.16 version. You will get things resolved, you do awesome work! Thank you for all your work and patience. Merry Christmas to everyone @ EZ Robot. Steve S


Can someone try this...

  1. uninstall all copies of ARC from your Programs and Features in the Control Panel

  2. and install this: Trial1Installer.msi


@DJ Sures... Tried no go, same errors. j


k working on another


How about this one.. Make sure you uninstall any ARC that you have previously installed from the Control Panel.


United Kingdom

This one worked for me on Windows 7 64bit :)

Note: I also installed the latest version of .NET


okay, this one worked for me on Windows 8.1 64bit.
