Seems that Adv Inst 9.8 has an issue in the rollback when the user cancel the installation in a specific process of the installation (Extracting files), this process happens almost at the beginning of the installation and it doesn’t last long. In the Media panel over the Archive section changing from LZMA compression to CAB allows a safe rollback but the behavior is odd:
CAB files case:
1. Hit “Cancel” when extracting files is going on, then click “Yes” to cancel the installation
2. Seems that the installation continues (Copy files) until an error message is found (disk1.cab not found), then click “Cancel”
3. Confirm with “Cancel” and the rollback will be safely executed
LZMA compression option case:
1. Hit “Cancel” when extracting files is going on, then click “Yes” to cancel the installation
2. Seems that the installation continues (Copy files) until an error message is found (<whatever file> file not found), then click “Cancel”
3. Confirm with “Cancel” and the rollback will be safely executed
Is there a workaround or fix for this issue?, since is confusing for normal users.
