The freely-available (from Microsoft) MOM connector officially only supports Framework 3.7.1 and 4.1. This poses a problem if you have Framework 4.1.1 installed however. Luckily, I found a fairly simple workaround so that I could successfully install the product on Framework 4.1.1.
The install checks the value of the "revision" attribute of the Installation object (youcan find the OID of this object with 'wlookup Installation') using:
idlcall $INSTALLATION_OID _get_revision
On a 4.1.1 system, this value comes back as "4.1.1". However, the install script is expecting "4.1" or "3.7.1". So to change this value, you can run:
idlattr -tsv $INSTALLATION_OID revision string '"4.1"'
(yes, that's double-quotes inside single-quotes around 4.1)
Then you can go through the install, and it should be successful. To set the value back, run the command:
idlattr -tsv $INSTALLATION_OID revision string '"4.1.1"'
And all is well.
