"Error 1001. InstallUtilLib.dll: Unknown error."


I have VS.Net 2013 with Arduino IDE 1.5.6-r2 on a Windows 8.1 Enterprise VM (running on Windows Server 2012 R2).

When I run the installer package (both the Release & Beta) for Visual Micro, I'm receiving "Error 1001. InstallUtilLib.dll: Unknown error."

Looks like [InstallUtilLib.dll bitness issue.

Please help.

Thanks for the update good to hear you found the solution.

Because we still support xp and vs2008, it is easier to have a single installer + a few common .net 3.5 files to reduce the compile time.

I installed .Net Framework 3.5 (includes 2.0 and 3.0) from 'Turn Windows features on or off' dialog. Installer successfully completed.
