Hello everybody. Nice to meet you all.

I recently installed manjaro and also downloaded wine to install a windows program I am being requested to use. The program is called manycam. I have tried several ways of trying to install the program but I always receive the same error. The program does install itself and creates an icon in my desktop but when I run it, it doesn't start. The crash report says this on the first line:

Unhandled exception: page fault on read access to 0x72676572 in 32-bit code (0x7ddd4b2b).

When I try to run the program using the terminal, I get this:

002c:fixme:winediag:__wine_start_process Wine Staging 5.12 is a testing version containing experimental patches.
002c:fixme:winediag:__wine_start_process Please mention your exact version when filing bug reports on winehq.org.

If somebody could give me a hand with this, I would appreciate.

I'm pretty sure you're out of luck. portcls.sys, at least is a hardware driver not implemented/cloned whatever by wine at this point. See for example: https://forum.winehq.org/viewtopic.php?t=34228

In general, Windows programs that interact with hardware directly, like a camera, particularly if they don't use a generic Windows port like com1 etc., are not supported with wine. One of the curses of using not linux supported open source stuff. Very popular programs, such as Zoom, support linux, even MS Teams does without using wine.

Thank you very much for your anwser. I'll have to see then how to install both windows 10 and manjaro and having them working fine. I just tried to install windows in another partition after having installed manjaro and the computer boots in windows and not in manjaro (the boot menu for manjaro has disappeared).

Sorry to hear that, it’s pretty recoverable; just have to boot from a USB, preferably running Manjaro, and reinstall grub. There’s about a million steps by step instructions for that out there.
