Swervomotor Posted May 19, 2020 Report Share Posted May 19, 2020 I routinely find myself bouncing between 3-4 different revisions of unilogic depending on what version the program on the controller was created on. I've only been able to do this by uninstall whatever version I have and re-install the version I need. Is there a quicker way to somehow keep multiple versions on the same box without having to go through the uninstall- install process?

MVP 2021 Flex727 Posted May 19, 2020 MVP 2021 Report Share Posted May 19, 2020 When you install a new version of UniLogic it asks you if you want to keep the previous version. Say yes. You will then have both versions installed. You can continue this as needed. I have 8 versions installed on my desktop right now. 1 Quote Link to comment Share on other sites More sharing options...
Swervomotor Posted May 20, 2020 Author Report Share Posted May 20, 2020 I just tried to install a later version on windows 10, checked the box to keep the old version and got this error box. If I pick "ok" it will un-install the previous version, If I hit "cancel" it exits out of the installer. Quote Link to comment Share on other sites More sharing options...
MVP 2021 Flex727 Posted May 20, 2020 MVP 2021 Report Share Posted May 20, 2020 Just click OK. The old copy is retained and will still run. 1 Quote Link to comment Share on other sites More sharing options...
MVP 2021 Ausman Posted May 20, 2020 MVP 2021 Report Share Posted May 20, 2020 @Cara Bereck Levy @AlexUT Is this a Windows controlled requester, or a Unitronics one? If it is Unitronics, the wording needs to be changed. If Windows, perhaps there is a workaround? Like Swervo, I would find this very confusing for it to do exactly opposite what it is saying. Especially when the "result" is what people are wanting to implement. cheers, Aus Quote Link to comment Share on other sites More sharing options...
Saragani Posted May 21, 2020 Report Share Posted May 21, 2020 Well, It's installshield and it is doing exactly what it says. The installer needs to uninstall the current version in order to install the new one, When you check the "Keep old version", it simply copies the current version to another directory, changes some config file, copies some other files to that directory, creates a shortcut, and only then asks you if you want to uninstall.

MVP 2021 Ausman Posted May 21, 2020 MVP 2021 Report Share Posted May 21, 2020 Saragani, if you had this requester come up without already knowing what the program did (as you have carefully and well described) you would no doubt be confused too. Perhaps your description of what happens when you keep old version needs to be inserted into the InstallShield wording. cheers, Aus Quote Link to comment Share on other sites More sharing options...
Cara Bereck Levy Posted May 26, 2020 Report Share Posted May 26, 2020 Hi guys, Sorry for the confusion. I will enquire about changing/adding something to the wording--but I know from past experience that Installshield is Installshield, and it is doubtful it will be changed...

stevel Posted October 24, 2021 Report Share Posted October 24, 2021 this does not work. The unistream still gets uninstalled and there is not copied file Quote Link to comment Share on other sites More sharing options...
AlexUT Posted October 24, 2021 Report Share Posted October 24, 2021 Hmmm... Everything is working. 1. I have a bunch of folders with previous versions of UniLogic: Where UniLogic is a last installed version (highest). 2. All uninstalled versions (from UniLogic folder) are in separate folders, numbered by version of uninstalled UniLogic. *You have to install lowest version first, than next one, and so one until you install last version. 3. If you have trouble - delete all numbered versions, than uninstall last installed version. Now download all required versions and start installation from lowest version number. 4. When you install UniLogic and previous version is already installed, Installer show you next pop-up: Where "Keep a copy of the old version" check-box is checked. *You have to right-click at each downloaded file, select "Properties" and click on "Unblock" button if it is presented. *If your login account has no administrative privileges, than you have to run installation "As Administrator". *Last UniLogic versions know to require administrative privileges to run installation and to run UniLogic itself. *You can run on old version of UniLogic, but cannot run 2 versions at the same time. *To run old version, you have to close currently used UniLogic and kill from Task Manager "Unitronics Notifier" (in "Background Processes". *Use shortcut to run an old UniLogic version, or run it from old UniLogic version folder by running "Unitronics.Shell.UI.exe". *Double-click on *.ulpr file running last installed UniLogic version. Hope this information will help to keep required versions at your PC. B.R. Quote Link to comment Share on other sites More sharing options...
stevel Posted October 24, 2021 Report Share Posted October 24, 2021 The folder copies are not being made and I am running the setup as admin. Can I do this manually ? After the copy is made and before the unistall, not new named folder exists with the old version name, Quote Link to comment Share on other sites More sharing options...

AlexUT Posted October 24, 2021 Report Share Posted October 24, 2021 Did you Unblock UniLogic installation file when download finished? If not - than Installer cannot finish some operations, requiring Administrative rights. Quote Link to comment Share on other sites More sharing options...
