I recently tried to install vSphere PowerCLI from VMware on my Windows 7 64-bit installation.

and i was met with the error message above.

theres probably multiple answers to solving this problem. some say that you need to run it as administrator permissions (doh) and some want you to change permissions on the

registry vmware path.

what almost worked for me was deleting the reg entry “HKLM\Software\VMware Inc” and then just retrying with the installation. i however, had to delete the entry

“HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\VMware, Inc.” for it to work.
