Terminal Service 2008 amd Crystal Report (registry trouble ?)

[Guest Porlock]

Hi everyone,

 

I develop an account software that use Crystal Report to obtain reporting

capabilities. My software supports three runtimes of Crystal Reports:

release 8, release 9 and release XI. The user can configure the application

and choose which to use.

 

Some installations (of our customers) use Terminal Server features: the

application is installed on the host pc (usually Windows Server 2003), and

the clients (running XP) connect to the host and use the software via

Terminal Service, and all works fine.

 

Recently one customer of ours has set up a Windows Server 2008, and troubles

began ! ... the Crystal Reports runtime failed to function. Let me try to

explain the scenarioes:

 

- Host PC with Terminal Service 2008

- User A on a PC with Windows XP

- User B on a PC with Windows XP

 

scenario 1, my application uses Cristal Report Runtimes XI

 

User A and B can correctly install the runtimes.

Both of the user cannot print reports due to a failure instantiatìing the

COM components of Crystal Report.

 

*****

scenario 2, my application uses Cristal Report Runtimes 9 ... the most funny

 

User A connect to the host, install the runtimes and start to use the

application. All works fine.

User B connect to the host, install the runtimes and start to use the

application. User B can use the application (and print reports) but suddenly

the User A failed to print (failure instantiatìing the COM components of

Crystal Report).

Well ... User A reinstall Crystal Reports library and newly register COM

components, and the application newly works fine (and print reports

correctly) ... but User B suddenly stop printing reports (the same error).

User B reinstall Crystal Reports library and newly register COM components,

and the application newly works fine (and print reports correctly) ... but

User A suddenly stop printing reports (the same error) ... and so on.

 

*****

scenario 3, my application uses Cristal Report Runtimes 8

 

User A and User B can correctly install the runtimes and the software works

fine !

Very funny beacuse ver. 8 of Crystal Reports Runtime are quite old, but they

works properly instead of rel. XI (more recent) that doesn't work at all !

Crystal Report runtimes use heavily Windows Registry, and setting up those

runtimes require a lot of registry update (due to COM interfaces) maybe

there is some registry issue/trouble that scramble Crystal Report runtimes

configuration ... the scenario 2 is quite bizarre and counfuse me !

 

Shall I need to configure some setting on Terminal Service 2008 ?

any idea ? thank you very much.
