Acrobat Xi failed to load its Core.dll in Xenapp 6.5 enviroment --can't open pdf files as result.

Hello All,

We have a problem with Adobe 10.1.3/4 and 11.

When we install the products onto the Citrix Xenapp 6.5 Servers, we can run the application the first time without anny error at all. However, when we close the application and try to open it again we get the error core.dll

When we repair the app, it will work perfect the first time again, then second we get the same error core.dll.

This happens on v11 v10.1.3/4 starts correct but there are many other problems with opening/self signing, placing comments and so on.

Therefore we installed v11 but now we get the core.dll error.

Are there any files/registry keys etc that we should be looking at or any other area of configuration that anyone can recommend.

Regards

William
