I'm trying to get a single user copy of Mathcad 12 to run on an old computer running Windows XP. I own copies of Mathcad 2.5, 4.0, 8.0 and 12. The program is going to be used in some work I am donating to a local non-profit. I acquired the software while working in 2005, and am now retired. The copies on the machines I used prior to retirement were all removed when I left.
The software installed without any error messages. The automatic activation window opened and ran without error. The C_DILLA directory was created, with a Safecast Product Licenses subdirectory containing a file which is modified every time I attempt to start the program. There are entries in the application logs for the event viewer saying installation was completed.
Does anyone have suggestions why the program won't run?
