During the installation of Diamonds/ PowerConnect (version 2017 until 2019r02), you get the error:
The specified directory, “C:\Program Files\Microsoft SQL Server\”, for the INSTALLSHAREDDIR parameter is not valid because this directory is compressed or is in a compressed directory. Specify a directory that is not compressed.
This error is related to the database system (= SQL instance) used by these versions.
- Install Diamonds/PowerConnect/BIM Expert 2020 or more recent. These versions so a different type of database, which no longer requires the installation of an SQL instance.
- On the desired folder (in this case “C:\Program Files”) right click and go to Properties.
- Click on Advanced button.
- Uncheck the box Compress the drive to save space
- Click Apply and then Ok.
- Let the process finish.
