what did you make? what does it mean "before was OK"?

I worked with these installations until last week and filled out my udfs without any problems.
For a week I did not use fluent ansys, and when I tried to compile the udf I had this problem.
I don’t know what happened
is it possible that it was an update of windows?

It looks like you forgot to unload your UDF.
