Calibre 5.0.1 Unhandled Exception

Submitted by paulvp on September 26, 2020 - 2:01am

I've just updated Calibre to version 5.0.1 and find that the program won't run. Instead I get an error window titled: Unhandled exception running calibre.
The error message says:
Unhandled exception running calibre
Traceback (most recent call last):
File "", line 89, in
File "", line 84, in main

File "site-packages\calibre\", line 71, in calibre

Foxit Reader not responding

I must say thank you so much for this awesome service I have made a donation and this is one of the best services out there as I never knew about portable apps before. I love the range of apps & that i don't have to continually update apps & i have far less issues since i went portable with my browsers.

Just today I had issues with Foxit reader not responding. I think there was an update at some point i can't recall. have a screenshot of error message:

GNUcash requires administrator rights (sometimes)

Submitted by paulvp on May 17, 2020 - 2:59pm

I'm experiencing a strange problem with GNUcash as follows:
When trying to launch the program from the portableapps menu via the usual single left click, nothing happens. I then found that using a right click and 'Run as administrator' launches the program just fine. However, sometimes, a single left click will still work.
So far, I haven't been able to establish a pattern of when the left click does/doesn't work. It seems to be random.

Hi, It's been a long time since my last post here but I'm still an active PApps user.
Question is as follows, I have a Calibre Portable installation in a USB drive wihtout anything else. Just the App and the library with dafault settings. This app is storing 1000 PDFs which are scientific papers about a specific subject. The intention is to allow colleagues to copy the USB drive so they can have the collection with them. I renamed the CalibrePortable.exe to something like ScientificJournals.exe and that's the only think I changed in that USB.

I'm having two issues
1) the FileOpen plugin is no longer working on the portable install (recently updated to version
2) there is a new FoxIt 9.7 version and I'm curious if my item above is because the plugin updated and is no longer compatible . In the plugins page, file open is not certified or loaded (no check marks, just a red circle with a diagonal line). cannot find a ZIP file to test and see if this is the issue.
