Cannot install mPOS again after I Uninstalled it

(0) ShareShare
ReportReport
Posted on by rody 120

I have D365FO 10.0.0.13 Local VM trial.

I installed mPOS for HOUSTON-3 device. It went successfully and i tested some transactions. 

Question: If i want to test mPOS application for another device like BOUSTON-1, do i need to download the configuration file and the modern POS file for that device and install them?

I am doing this on the VM for testing and learning purposes.

    Hi Rody,

    Glad to hear it works. That should be a working folder created by installer temporarily, to put the extracted content from compressed installer package.

    Based on the error, your issue looks like related with a previous installation and somehow those file/folder not accessible by new installation to rewrite them. So deleting the folder helped.

    Thanks,

    Juliet

    Hi Juliet,

    It is working now after i deleted the folder C:\Users\Administrator\AppData\Local\Temp\ModernPosSetup.content\

    What is this folder about?

    Thank you.

    regards

    Hi Rody,

    This error seems not happening in my demo VM.

    Have you tried delete this folder? C:\Users\Administrator\AppData\Local\Temp\ModernPosSetup.content\

    You may also run this installer and see if any difference: C:\RetailSelfService\Packages\ModernPosSetup.exe

    Thanks,

    Juliet

    Hi Juliet,

    When i uninstalled mPOS, i went to the list of 'installed programs' in control panel\programs and features\

    and i restarted the server but the error still showing each time i try to run 'ModernPOSSetup_V104259421438'.

    Hi Jeffrey,

    I have done a lot of work on Dynamics 365 (creation,setup of legal entities/import of data..etc.) which requires backup of the AXDB and restore after wiping the machine and starting over . I will consider that if no other solution...

    Hi ToddB,

    Yes that is clear but, unfortunately the mPOS is uninstalled and i am not able to re-install it again because of the error that shows in the above screen shots.

    Reinstalling windows takes 10 minutes... if you cant uninstall/reinstall MPOS, just wipe the machine and start over. Far less time than troubleshooting. Then, going forward, just reset and reactivate.

    Hi Rody,

    If you did this on Start menu, "right click on it and click Uninstall", it only uninstalls the Windows App from your current user.

    Now if you open Control Panel -> Programs -> Programs and Features, and pull out a list of all installed programs, can you see "Microsoft Dynamics 365 Commerce - Retail Modern POS" there?

    If yes, it's not completely uninstalled from your system.

    Go ahead uninstall it from here and see if you can re-install the MPOS.

    Again, as other replies mentioned, you really don't need to uninstall the MPOS, if you only want to switch device. Re-activating MPOS (AKA reset MPOS) should be enough.

    Regards,

    Juliet
