I installed Vista under Microsoft Windows using InterSystems Cache using a CACHE.DAT file. Do I now have the CPRS program?
No. You have the server code and data in the CACHE.DAT, but not the client side code.
The CPRS program is actually a separate Microsoft Windows executable. Before version 26, it was only a program named CPRSChart.exe that could be anywhere on your system. Since CPRS usually needs to know how to contact the VistA server, most people use a shortcut to start it. After version 26, a separate DLL is also required named "BORLNDMM.DLL" which handles some memory management for CPRS.
