A few weeks ago I formatted my laptop where among other things QGIS 3.4 was installed.
In the last 48 hours I was busy trying to reinstall it, but until now without succeess. I have a Thinkpad with Windows 10 PRO. I installed versions 3.4 and 3.2 several times: everything goes well but I do not get the launch icon and in "ProgramFiles" the postinstall.bat icon gives the message:
Windows cannot access the specified device, path, or file. You may not have the appropriate permission to access the item.
With a Windows technician I have checked all the admin settings in my PC. We also have created an administrative account. Same issue.
Edit: I have installed using OSGEO4W. It was installed not only QGIS 3.10 but also a lot of software which I would like to get rid of. When I open QGIS I ge this message: ' An error has occurred while executing Python code:
*PermissionError: [WinError 5] Access is denied Traceback (most recent call last): File "C:/OSGEO4~1/apps/qgis/./python/plugins\processing\algs\saga\SagaAlgorithmProvider.py", line 86, in loadAlgorithms version = SagaUtils.getInstalledVersion(True) File "C:/OSGEO4~1/apps/qgis/./python/plugins\processing\algs\saga\SagaUtils.py", line 141, in getInstalledVersion universal_newlines=True, File "C:\OSGEO4~1\apps\Python37\lib\subprocess.py", line 756, in init restore_signals, start_new_session) File "C:\OSGEO4~1\apps\Python37\lib\subprocess.py", line 1155, in _execute_child startupinfo) PermissionError: [WinError 5] Access is denied
