SymptomsGetting the following error message when attempting to perform minor (7.5.0 to 7.5.5 or 7.5.5 etc) Plesk updates:
Another version of this product is already installed. Installation of this version can not continue. To configure or remove the existing version of this product, use Add/Remove programs on the Control Panel.
ResolutionThis error means that you ran full build installation or web installer instead of Plesk patch. To update Plesk you need to download and install an appropriate patch.
You need to update your Plesk 7.5.0 to 7.5.5. To do this you need to download plesk_patch_7.5.0_to_7.5.5_build051007.11.msp from our web site and install it.
