"An unsupported process was attempted" Cant install on VISTA ULTIMATE 64BITS

I’m trying install CIS a long time, due to some incovenientes with OUTPOST. But every time I try install the CIS the following message error appear: “An unsupported process was attempted” I try install all versions since 3.5 to 3.8 and still giving the same mistake. The version downloaded is 64bits, I never install COMODO in my pc. Already clean the register and I have tried an installation of safety and in diagnostic, has not worked.

Someone could help me to install the CIS?
