Corel KPT Collection 7 Problems on Windows 7 64-bit?

My PC Configuration: 1. Windows 7 64-bit. 2. Photoshop CS4 installed in two versions- 32-bit and 64-bit. I try to install Corel KPT Collection in Photoshop CS4 64-bit folder - installed without any problems but KPT not support 64-bit Photoshop CS4 and KPT plugin not presented to use in Photoshop CS4 64-bit. I Uninstalled KPT Collection 7 without problems and tried to re-Install in Photoshop CS4 32-bit folder but at installation process I received the message that Installation Process Cannot Install UNinstaller Program for KPT 7 and installation process cancelled with Windows 7... I have tried to install KPT 7 some more times and received that message and process cancelled, But on the third time I could make installation and KPT-7 installed succeful... and presented to use in Photoshop CS4 32-bit version, but... But as I wish to open and use KPT Plugin in Photoshop CS4 each time from me it is required to enter serial number again... When I have tried to Uninstall Corel KPT 7 Collection I could not to make it because the UNinstaller for KPT 7 not presented and Corel KPT 7 not listen in Windows program manager - I can't to uninstal KPT 7 from system and I cannot use KPT 7 if he demands from me each time to enter serial number. I searched for possibility for reception of the direct help from Corel on email but could not find! It was necessary to write here...

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. 

I am very glad that there are people which can to help. Also it is very upset by disgusting quality of official technical support from Corel. Thanks you dr.
