When installing your Sage software, the following message may appear:

'Error 1723: There is a problem with this Windows installer package'

This is due to an issue with Windows Installer. To resolve this follow the steps below.

There can be a couple of potential ways to fix this, so we'll explain both methods below:

Temp folder permissions

The error can occur if you don't have the required access permissions to the Temp folder. To rectify this:

1. Open Windows Explorer by holding down the Windows key  and press E.
2. Enter C:\Users and press Enter.
3. Double-click the username you are logged into Windows with.
4. Double-click the AppData folder.
5. Double-click to open the Local folder.
6. Locate the Temp folder, then right-click and select Properties.
7. In the properties window, click the Security tab.
8. Click Edit to modify your user permissions.
9. Ensure your username is selected, and tick all boxes in the Allow column.
10. Click OK then OK again to close the properties window.

If you're still not able to install the software after completing the above steps, continue to the section below.

Reregister MSIEXEC

1. Press and hold down the Windows key and press R.
2. Type CMD then click OK.
3. Type MSIEXEC/UNREGISTER then press Enter.
4. Type MSIEXEC/REGSERVER then press Enter.
5. Type Exit and press Enter.
6. Install the software again.

Once you've done the above, we'd recommend enabling the hidden admin user account and installing the software under that login if the issue continues. Refer to this article for more information on enabling the hidden admin account.
