PowerCLI New-VM or Set-VM: Could not load file or assembly ‘CryptoSupport.dll’ or one of its dependencies

I was trying to clone some VMs and apply an os config to it without any luck. I kept getting this error about CryptoSupport.dll and google wasnt helping me much.

After much digging I found that the CryptoSupport.dll is 32bit only and my ISE running in x64 wasnt too happy about loading it.


So, load 32 bit powershell.


Error looked something like this:

Could not load file or assembly ‘CryptoSupport.dll’ or one of its dependencies.  is not a valid Win32 application. (Exception from HRESULT: 0x800700C1)

    • I tried a reinstall. found a vmware post some place that stated that there was no 64bit option for it, if you run powercli on your box it looks for the 32bit version. I always embed these things in to my main profile so that I can have one console to do all work. Just need to be aware and load the 32bit version when im doing os configs.
