Hi, can you suggest a solution?

[mmozeiko]

Did you unpack all files from zip archive? Including qt.conf and platforms\qwindows.dll? Maybe you copied exe file somewhere else and didn't copy other dll/conf files with it?

[ozgurulukir]

Yes, i just unpacked zip archive (whole files) and rclonebrowser was not started with that message, maybe packed dll files are wrong?

[mmozeiko]

Hmm, I am pretty sure all dll files are in the zip. I am able to run 32-bit exe just fine on 32-bit win7 (clean win installation in VM, no previous software).

Are you sure you unpacked all files when running exe, and you are not running from explorer "zip" folder (it opens zip files as folders)?

Can you try running cmd.exe then setting path to platforms folder to QT_QPA_PLATFORM_PLUGIN_PATH variable like this:

set QT_QPA_PLATFORM_PLUGIN_PATH=c:\path\to\rclone-browser-1.2-a1156a0-win32\platforms

and then execute RcloneBrowser.exe like this (in same window):

c:\path\to\rclone-browser-1.2-a1156a0-win32\RcloneBrowser.exe

Does it run like this?

Another thing to try is DebugView: https://technet.microsoft.com/en-us/sysinternals/debugview.aspx

1. download & run it

2. open cmd.exe and execute:

   set QT_DEBUG_PLUGINS=1
   C:\path\to\RcloneBrowser.exe

3. Go to debug View and save log, and paste it here.

Maybe you can show screenshot of folder structure you are running exe from?

hi, it same, i did as you described, could this problem related with my version of windows which is Vista?

here debug log

Oh, Vista. I was not thinking about it at all... Now when I run it in Vista VM I get exactly same error. I'll need to check what I need to change to support it on Vista. It should be possible to run it under Vista.

[ozgurulukir]

Thanks, but if this related with old vista, dont spend your time for this because i think there is possibly no solution.

[mmozeiko]

It seems Qt supports Vista only up to 5.6 version: https://doc.qt.io/qt-5/supported-platforms-and-configurations.html

I've build binary with Qt 5.6, can you please try it out and let me know if it works: https://drive.google.com/uc?export=download&id=0B6NdBDx_PciXV3FiSTNZRWxja3M

If it works, I can simply use Qt 5.6 for 32-bit builds.
There is only one minor difference from newer Qt versions - GUI doesn't refresh remote list automatically after rclone console is closed (when "Config" button is pressed). That was I just simply disabled so I can build new binary quickly.

[ozgurulukir]

Thank you you are so kind, QT 5.6 build is working.
