Appendix J: Installing the .0 and .1 Releases of the Same
PC*MILER Version
You cannot have the “.0” and the “.1” release of version 14 or 15 on the same
PC because they share a common Registry Key. For example, if you need
access to versions 14.0 and 14.1, you will need to install 14.0 on one PC and
14.1 on a second PC. For Version 16 and higher it is possible to run both the
.0 and .1 releases on the same PC. However, doing so does complicate the
installation process. Starting with the release of V24 both the .0 and .1
releases install on the same PC with no extra configuration steps.
NOTE: You must pay strict attention to the installation process or you run
the risk of corrupting or overwriting existing installations. There are three
areas that need attention: Shared Installation GUIDs, Default Installation
Locations, and DLLPath Configuration.
NOTE Also: There are .1 specific builds of the installs available. Depending
on the vintage of your software, your .1 setup.exe’s and MVS self-extracting
Zip files may default to a Pmwxx1 directory.
For example, Version 16.1 defaulting to Pmw161.
Shared Installation GUIDs
For Version 16.x, 17.x, and 18.x you will have to delete a reference to the
previous release installation (.0 or .1) before you can install the second
release.
After installing the .0 or the .1 release and before you install the second
release, run Regedit.exe and delete the following keys:
