Caché Installation Guide - InterSystems Documentation

enable a previous Caché instance to use the compatible local files, rather than a newly installed current
Caché set of registered executables.
To create .local files for all the executables in a directory type the following at a DOS prompt:
for %c in (*.exe) do set tempvariable= >%c.local
For more information on .local files see the Microsoft article entitled: The End of DLL Hell.
2.5.1.1 Register Files
The Caché installation contains a Regfiles.bat script file in the install-dir/Bin directory that reregisters
object tool files in a common Caché directory. You require Administrator privileges to run RegFiles.bat.
You only need to run this script if you install or uninstall any instance of Caché 4.1 or earlier; if you
are only running instances of Caché 5.0 or later, the object tools function properly with multiple
instances.
Here is an example of running the script:
C:\MyCache\Bin>regfiles.bat
C:\MyCache\Bin>rem Register Cache Self-Registering executables in
common directory
.
.
If after running RegFiles.bat, you still receive errors similar to the following when you start Studio:
Cannot create class factory for COM_SLSID_TNodes
Run the script with the ALL argument; this reregisters all JCOM DLLs in addition to the other files.
For example:
C:\MyCache\Bin>RegFiles.bat ALL
C:\MyCache\Bin>rem Register Cache Self-Registering executables in
common directory
.
.
C:\MyCache\Bin>rem Register JCOM dlls
C:\MyCache\Bin>set CacheDir=C:\MyCache\bin\
.
.
Special Considerations
Important:
Running RegFiles.bat ALL when it is not necessary will prevent the uninstall procedure
from removing some registry keys under HKLM\Software\Intersystems when you
uninstall the last Caché instance.
