Occassionally it may be necessary to perform a clean installation of the SCRATCH software.
This can be done without losing any User or Project settings by following these simple steps:
1. Exit out of SCRATCH.
2. Create a new folder called BACKUP in a convenient location.
3. COPY the following folder into the BACKUP folder:
- Mac: \SystemDisk\Library\Application Support\Assimilator
- PC: C:\ProgramData\Assimilator
Note: Be sure you COPY the folders.
4. Select START->Control Panel->Uninstall a program
5. In the list of programs that appears, select SCRATCH and click UNINSTALL (or double-click SCRATCH)
On the Mac, just drag the SCRATCH application from the applications folder into the trashbin
6. Once SCRATCH has been removed, DELETE the following folder:
- Mac: \SystemDisk\Library\Application Support\Assimilator
- PC: C:\Program Data\Assimilator
7. Install SCRATCH.
8. Run SCRATCH
9. Copy the SCRATCH license key from the licensing email you received during the initial setup to the license activation window at the Start up screen. Then Activate.
10. Exit SCRATCH
11. Copy any customized folders and files [such as User or Project folders] from the BACKUP to the corresponding folder in the new installation.
This will give you a fresh installation of SCRATCH while keeping all of your current work intact.
