Sage 50 CA Clean Re-Install Tips

Does your machine have lots of old installs of Sage 50CA? Are you looking to wipe your system to "start" fresh? Below are resources on how to backup your data, wipe your system of Sage 50 install history and then re-install and restore your company data files.

STEP 1: Backing up your company database

Before removing Sage 50 CA software from your machine. You will want to backup any company database files which reside on there. Doing this, ensures that you have files available to restore after the re-install if you need them. Normally, backup files are saved outside of your Sage 50 install's directory anyways, so even if you miss this step, there's little worry of removing data permanently. Still though, we recommend saving copies of your data in multiple locations. See our post on Sage Drive (FR post here) and on cloud based Office 365 One Drive backups if you're interested in having secure backups which are kept off premise in the event of a natural disaster type of occurrence.

Start by checking the integrity of your company data file, then create a backup and finally once you have a fresh install available, restore the data files you need.

  • I am trying to enter hours of overtime for an employee, but it doesn't come up as an option in the payroll journal under the income tab.

    I have the boxes checked for our employees so that they do receive overtime, but it isn't letting me enter overtime hours. All I have is regular hours worked.

    Any ideas?
