FS9 UT EUROPE ERROR CODES 21FC & 11FD

I recently made two attempts to install UTE in fs9 but kept getting a different invalid data error code (21FC & 11FD) each time. The first time I used my original download version (error code 11FD). The second attempt (error code 21FC) was a fresh download from Flight1's website. Here's what I did to solve my problem. A second fresh install of fs9 (with fs9.1 patch) . I had no problems installing it using my original 6 months old download version. The problem had nothing to do with bad memory or having over 4g of memory. I believe it had to do with other scenery which I had previously installed in that area of the world. Maybe, UTE needs to find and rename certain bgls file to install properly and when it can't it automatically shuts down and produces an error code. Anyway it runs as advertised.
