Hi,
When installing LibreOffice 6.2.0 I’ve just got the same error: The system cannot open the device or file specified.
Follow the instructions ‘How to enable Windows Installer logging’. Put into Value data field all options: voicewarmupx.
Run the installer again.
After it fails, go into C:\Users\your_user_name\AppData\Local\Temp directory. Find in it the most recent .LOG file, something similar to MSI5093e.LOG.
The log will give you some clues about what and why the installer couldn’t open.
In my case I have C:\e directory mounted as E: drive. The installer or Windows 10, version 1809, I upgraded it on 2/17/2019, incorrectly interpreted E:\ path:
MSI (s) (D0:84) [23:11:07:693]: Error: Wrong Long Path Name:
E:\downloads\LibreOffice\LibreOffice_6.2.0_Win_x64.msi
MSI (s) (D0:84) [23:11:07:693]: Error: Wrong Path Name: \?\C:\e\downloads\LibreOffice\LibreOffice_6.2.0_Win_x64.msi
MSI (s) (D0:84) [23:11:07:693]: Error: This file path is updated, hence failing to create: E:\downloads\LibreOffice\LibreOffice_6.2.0_Win_x64.msi
MSI (s) (D0:84) [23:11:07:693]: Note: 1: 1309 2: 110 3: E:\downloads\LibreOffice\LibreOffice_6.2.0_Win_x64.msi
The system cannot open the device or file specified.
It is the first time after the Windows update I am installing LibreOffice. Something got changed.
I’ve been installing LibreOffice from E: drive since version 4.0 without any problems.
This time I had to install it from C: drive.
PS. Don’t forget to remove Logging from Registry.
