Good morning, hope you are well.
If you go to the CS shop, there is a page for customer support and installer errors. https://www.captainsim.com/support/
That page links you to an L1011 post on the forum which outlines all of the steps to take if you have install problems.
https://www.captainsim.org/forum/csf.pl?num=1534366436
If you have tried everything in sections A,B and C it gives you details how to contact CS under the title “For all other products please PM to this account providing” which is the bit you will need.

Cheers and good luck  :)
