installing QGIS

What is the bug or the crash?

I want to install QGIS not on C drive but my D drive and still the software tells me that there is not enough discspace on C drine. But everything must be installed on my D drive.

This is for 3.34 and 3.38 version. In the past installed 3.30.0 without any problems

I have acually almost the same problem, C: full, D: has enough space, but despite choice of a Dir in D: it does'nt work. Only difference to Marks2023: I'm beginner and because I can not install QGIS at all, I can not change the profile file.

@Marks2023 @JoKra8833, thanks for reporting. Did you use the all-in-one stand-alone QGIS-OSGeo4W-*.msi installer or the OSGeo4W network installer osgeo4w-setup.exe?

I used the all-in-one stand-alone QGIS-OSGeo4W-*.msi installer, because I'm beginner with QGIS. Regards Jo

@jef-n, have you seen this issue report? Please see also https://gis.stackexchange.com/questions/487551/cant-install-qgis-3-40-on-d-drive.

That's because the Windows installer copies the MSI to %TEMP% and later to %WINDIR%\Installer, which are both usually located on C:. AFAICS that cannot be changed. And it should have been that way since we switched from NSIS to MSI. Using osgeo4w-setup.exe will use less space (although %TEMP% will also be used to download and cache packages by default) and moreover open the option to install less packages (eg. leave out Oracle support).
