When Statistica launches but not work as expected, then there may be problems with corrupt files. 
For example, a user may experience the following scenario:  "When working with working with generalized linear models, no dialog box or program windows appears.   The previous day, Statistica was working without any issues but now when Statistica is launched, it opens but no dialogue box or program window comes up with generalized linear models.   Seems like every other test works but this specific test is failing to execute."

Cause:  One know cause is corrupt system files or corrupt Statistic application files.

 

Windows operating systems only.
