Check you have .net framework installed. If so, re-download it and try again.

The ARC installer works fine.

see that it is unblocked before installing. and dont change the name off the download.

You might have to re-download it.

@Alexs, are you downloading and installing the latest version of ARC? Are you installing this on a PC with Windows 7 or higher? Do you have the Microsoft .Net version 4.5 installed? If not you'll want to install it. If you do have it installed already I would recommend reinstalling it and trying the install of ARC again.

I repaired the .NET framework as I already had version 4.5.1 installed. Then I removed it completely and re-installed it. Then I downloaded the installer again and this time encountered a different error. I am installing on a Windows 7 64-bit Lenovo X1 Carbon.

Nomad18.08 what do you mean by unblock, did your antivirus prevent installation?

i mean the download is blocked when you have win7. go to the download from ARC and click right mous and see below. avery download comes always from another pc.and carry another name. thats why your pc blocks it.dont change any names from download. just unblock it before installing.

So it's still not working. Nomad18.08 its strange, I never even knew that "blocking" existed and I have been a Windows user for many many years. I followed your advice and unblocked the download and made sure that the name was the default name "ARC Installer", mine did not have a strange name.

I am still getting errors ranging from the cabinet file error to an ixoFileCopy that was called out of sequence.

I have removed and reinstalled the .NET framework for a second time after unblocking the download. It did not help.

As of today 7/26/14 approximately 8 PM, the Windows client download link seems to be broken. When it is fixed I will re-download the program again and try once more.
