I am having troubling installing vpn 5.0.7 over 5.0.5. I created .mst to get it branding with my company logos, however when I install the msi with a bat file I realize I have 2 versions shown in add/remove. I tried entering values in upgrade table, properties, and executive processes and the uninstallation worked, but I get error messages.
If I put removeexisting product before or between install initialize I get error saying "error custom action - file missing... insthelp.dll.
If I put removeexisting product after installfinal I get "deterministic error".
I tried values or 256, 513 and 517 in the upgrade table and other methods, but couldn't get it to work.
1.for the first error I just keep pressing yes to the popup errors and the install will finish fine.
2. for the second error I will have to install twice before the install will get pass "deterministic error"
I need to deploy this vpn update to my clients and hope someone can give me some advice.
