Cause:
The NOAH 3.6.1 installation is designed to first install all the prerequisites for NOAH, then remove any existing NOAH installation, and then install NOAH 3.6.1. Therefore, if you receive an error during the prerequisite installation, your existing version of NOAH System will continue to function until this problem can be resolved.
In the case of the above error “Failed to install Pre-requisite software … Error code: 945”,some existing Microsoft database files have had their attributes changed to compressed. This typically happens during a disk clean up operation. These files are compressed to save disk space. The NOAH prerequisite installation cannot upgrade these compressed files and the prerequisite install fails.
Solution:
Follow the below steps to change the file attributes and then you can re-run the NOAH 3.6.1 upgrade.
- Reboot the PC
- Go to C:\Program Files\Microsoft SQL Server\MSSQL$HIMSA\Data.
- Locate the files msdbdata.mdf, etona.mdf, etona_log.ldf and msdblog.mdf.
- Right click on the files, choose Properties and Advanced.
- Remove the check mark from the box "Compress contents to save disk space".
- Click OK and the OK.
- Re-run the NOAH 3.6.1 installation.
