FAQ
Update to Clarity 7.0 will change the installation folder structure. How can I preserve the previous Clarity installation data in case I want to revert back?
In Clarity version 7.0 a new organisation of the installation folder structure has been implemented to separate the program files (*.dll, *.chm), configuration settings (*.ini, *.cfg) and the user data (*.prj, *.cal).
During the update, the installation wizard will automatically move files to new locations. Once this is performed, it is not easy to revert to the previous version (i.e Clarity 6.2).
Suppose that you have Clarity version 6.2 and you want to update to Clarity 7.0. To make sure that you can revert any time after updating to Clarity 7.0, perform the following steps:
- Make a backup of your projects, chromatograms, etc.
- Uninstall the current Clarity version (6.2).
- Start the installer of Clarity 7.0 or higher.
- Change the Destination Folder to C:\Clarity7 or other.
(Otherwise, it would be installed over the previous installation.) - Set data location to C:\Clarity7\DataFiles.
- Finish the installation.
- Change the Destination Folder to C:\Clarity7 or other.
- To preserve your original configuration, copy the following configuration files from the original installation (6.2) to the new installation (7.0) CFG subfolder:
- Clarity.cfg (and potentially any other *.cfg files)
- Clarity.dsk (and potentially any other *.dsk files)
- Clarity.sno
- Clarity.psw
Reverting to previous Clarity
When revert is needed, perform the following steps:
- Uninstall the new version (7.0)
- Install the previous version to the original installation folder (C:\Clarity). The one used before the update to 7.0
If you already updated to version 7.0 in the same directory as you have installed the previous 6.2 version and did not make a backup of the previous directory, you can revert using this procedure:
- Install Clarity 6.2 to the new directory
- Manually copy the configuration files (*.cfg, Clarity.sno, Clarity.psw)
- Transfer the projects with all the data by preferably using Archive/Restore commands, simply copying them to the Clarity folder can pose some risks.
Note that once you update to Clarity 7.0, Desktop files (*.dsk) are not compatible with previous versions of Clarity (6.2)!
