I installed PSE11 succesfully but cannot open because of two warnings:
1) The procedure entry point HandleWindowFont could not be located in thePLUGIN.dll.
2) .. Topaz plugin is either not designed to tun on windows or it conyains an error...
I can probably fix the second one by myself.
How do I fix the first point?
This seems to be some custome plugin from organisation topaz installed in the root directory which is stopping the PSE to launch.
Try to uninstall any plugin like that and it should work.
Topaz plugins are fully compatible with PSE11. There's no need to to uninstall them. Just ensure that they're installed in the correct folder according to the directions on the Topaz website.
