pb accessibility files allow access, but cause a problem

[Former Member]

Hi.  We have a customer who runs our pb 12.5 app from Citrix.

They recently applied, what the customer identified as "Hotfix2" to the Citrix 6.5 servers which run our app.

After Hotfix2 was applied, users were unable to login to our app and would see the message, "Error loading library.  Please check whether the Powerbuilder Accessibility Library can be located in the path."

When we placed pbacc125.dll in the path, the error message disappeared and users were able to login, but later, the app would freeze at different places.

Our customer's Citrix Admin then rolled back Hotfix2 and all was well.

Some questions...

- are there switches in Citrix config which might govern the need for pb accessibility files?

- why might our app be hanging with hotfix2 and pbacc125 in-place?

- what might be our best next step?

Any thoughts/suggestions appreciated.

Thanks,

Doug

Are you certain the pbacc125.dll file you placed on the citrix machine is the exact same version of your installed DLLs for PB? Version mismatches can cause some weird problems that are nearly impossible to predict or track down logically.

If it is the right version of the dll, find out what the hotfix covers and where/how it may be interacting with your app.
