1) To estimate which patch level that an installation of the Microsoft Project Interface is on, you'll need look into the following directory
C:\Program Files (x86)\CA\PPM\CA PPM MSPInterface\Bin.
This may vary depending on the bit-level of the Microsoft Project Interface that was installed (i.e., it may be located in the 'Program Files' sub-directory and not the 'Program Files (x86)' if it was 64-bit), and might be a different root location if this had been customized during the installation.
2) In that directory, depending on the version of the interface that had been installed (i.e. new or legacy driver), locate the corresponding below file
- caMspXml.dll (for the new driver)
- MSPapi.dll (for the legacy version)
3) Take note of the date listed in the 'Date Modified' field of your given file. This date can be used to indicate which patch level of the interface is installed
For example, for a PPM 15.1 Patch 10 installation of the Microsoft Project Interface - New driver, the caMspXml.dll file has a 'Date Modified' value of 4/3/2018.
4) Look at the 'CA PPM Cumulative Patch Summary' page for your base version of PPM in the CA documentation site. The one in the link provided points to that version of the page for PPM 15.1.
5) Look for the patch that has a release date closest to the date you took note of from earlier.
For our example, the patch for 15.1 that has a release date closest to 4/3/2018 is 15.1 Patch 10, which was released on 4/11/2018.
Using the steps above, you can estimate the patch level of an installation of the Microsoft Project Interface. In our example that you followed along with, the interface had been downloaded from PPM 15.1 Patch 10.
