Stupid Corel support - no one more Corel software to purchase. No email direct support, no help.
KPT Collection and many many other plugins do not work in CS4 64 Bit. The plugins have to be rewritten for 64 Bit and few plugin manufacturers have yet done so. Considering Vista wasn't even officially supported by the KPT set, I am not surprised you are struggling with installation on Win 7.
I have successfully installed and run the KPT tools on Win Vista and Win 7 both 64 bit but only the 32 bit version of CS4 will run them.
To get around the problem.
Launch PS CS4 in XP Compatiblity mode as an administrator.
Invoke the plug in. Enter your serial number.
Close CS4
Reopen in Normal Compatibility mode and it should be fine.
I posted instructions for this on the CNews server two years ago but I see it has been cleaned off.
Good luck.
Thanks for posting this. I was getting annoyed that I had to type in the serial no. every time I wanted to use one of the KPT Collection plug-ins in Painter 11 and PS (32bit) on my Windows 7 64bit system.
I did exactly as you said, went into the Properties for each program ( for those who don't know how - right click on the Program .exe file (or shortcut) and you'll see Properties at the bottom of the drop down menu - select the Compatibility Tab), selected XP SP3 Compatibility and Run as Administrator. Then opened the program, and chose a KPT plugin (and it didn't request the serial). Then shut down the program and went back into Properties turned off the XP compatibility and unchecked the Run as Administrator and everything worked perfectly after that.
Cheers Rikk!
