I'm using Vista x64 SP1
I right click on the removewatermarkx64.exe and run as administrator
it just asks me do you really want to apply this patch? and I type y for yes.
I get these Watermark string is not found. msgs and the watermarks are still there.
I ran your v0.8 on the evaluation version of Win7 x64 Enterprise (English). It removed some but "window license is expired" is still here. Does your program look for this string? May be an update of your remove watermark program is needed?
Thx for the great work though.
