Install of new version destroys old version after failure tgo install

[WzeroMN]

I opened Imatch 2017 and got message tat new version available. I downloaded the installer and tried to install the new version just released. It ran part way but then got a message that installer has insufficient privilege and should log as administrator. It wanted to use Desktop Public directory if I remember correctly. I switched user to administrator and tried again and got the same message. I have always installed from a standard user account but gave the admin password when asked. Never had a problem before but even trying from Admin account it fails.

Now I have no version. The old one does not exist anymore and I cannot install the new one in any account.

I am now without any version of Imatch.
Please help.

Obviously I cannot find an answer in help since I no longer have an installation :-)

Windows will automatically prompt you via UAC when it runs the installer. Same as IMatch 5 always did, fully automatic.

To me this sounds like the installed file is either damaged or you have downloaded it into a folder that has some sort of restriction.

1. Check that the file is OK bny right-click in Windows Explorer and then click on Digital Signature.
2. Move the downloaded file into a regular folder from which you are allowed to run software.
3. Maybe just delete the downloaded file and download again.

You can also use Windows Installer to create a log file during installation. This may help us to figure out why the installer is making problems on your system:

1. Open an Admin Command Prompt.
2. CD to the folder containing the downloaded installer file.
3. Enter

msiexec /i imatch_licensed_2017_6_2.msi /l*v MyLogFile.txt

This will record information about the install process, errors encountered and suchlike.

I've just installed all recent versions of IMatch 2017 (2017.5.4 +) on top of each other. On a machine with IMatch 5.8 installed and on a machine without IMatch 5. No problems with the installer or permissions. Windows 7 and Windows 10. Looks good.

I should have  done the download again. Not sure if that was the problem but it did fix it. Digital signature of the old file was good.

Thanks greatly for implementing the map scale on Google Maps. Ig works fine.
