I have a question about the Installable Web App.

Right now, we have an extremely complex large 12 year old app that runs lots of "medical type" offices from a citrix server.

The app uses several 3rd party OCX'x/DLLs.

I tried to run a sample app using one 3rd party OCX (A scheduling OLE object) with the trial version of PowerServer and it doesn't work. It does seem to work as an IWA. The question I have is, do these OCX's need to be installed on the client machines as well as the PB runtime and other dlls? The Schedule object requires several registration keys and we don't want to do this company wide since there are thousands of PCs that would need it. Does IWA act like CITRIX where it runs on the Server and gives a Visual representation of the app that the user can work with?

Hi John;

  The IWA architecture is such that your PB App's will run directly on the client PC's. Thus, if your App's need 3rd party DLL's in order to process - these will be downloaded to the client PC from PowerServer when the IWA is first run. You can designate to PowerServer to deploy these DLL's and register them on the Apps behalf automatically - however, you may need to have the IWA App run the 1st time in "Admin" mode in order to accomplish the DLL registration task. Then the IWA Apps should work OK in normal mode after that.

Regards ... Chris
