VI Toolkit 1.5 + VUM = Error

I was experimenting with the VUM Powershell library. I ran the Get-Baseline cmdlet and then the following error occurred:

After some digging around at goolge and vmware.com. I found that  the VUM library doesn’t work with the new version of the VI Toolkit. VMware is aware of the problem according to the post from Carter on VMTN and the Release notes:

Carter Shanklin posted this information on VMTN:

Hi everyone,

There is an incompatibility between VI Toolkit 1.5 and the VUM cmdlets. For now if you need to use the VUM cmdlets you will need to do so on a system that has VITK 1.0 installed.
This incompatibility will be resolved by a minor update to VI Toolkit that will be shipped when the next version of VUM ships. The next version of VUM will have cmdlets that support that version as well as the current version.

We’ve updated the release notes to note the incompatibility. Sorry for the inconvenience.

From the release notes:

VI Toolkit (for Windows) 1.5 is not compatible with VMware Update Manager – PowerShell Library 1.0.

To fix this “problem” I removed the VI Toolkit v 1.5 and installed the VI Toolkit v 1 again. After the rollback, the VUM library is working again :-).

I hope that VMware will fix this soon.
