Revo Uninstaller Portable

I have Revo Uninstaller Portable on XP 32 & 7 64.

On XP 32 I have 32 Bits 7zip & Revo Uninstaller shows 7zip under Uninstaller, this is fine.

On Win 7 64 I have 64 Bits 7zip & Revo Uninstaller doesn’t shows 7zip under Uninstaller, any info?

only revo uninstaller pro shows 64 bit applications.

But its showing CIS, CIS is also 64 Bits on Win 7 64, m I right?

weird, im not sure then
