Unable to launch v2.1.0.8 using Windows command line or through .BIN file association about vcc HOT 11 CLOSED

My previous fix made VCC without a command line unstable. A patch for that has been merged, there is a build here: https://github.com/ejaquay/VCC/files/12466820/vcc20230829.zip

from vcc.

I've pulled the latest source and was able to build successfully with Visual Studio 2022 using MSVC v140 - VS 2015 build tools. Looking into the issue here as well.

This should be fixed in V2.1.8.1

For command line I suspect you are having a path issue. First try fully qualified vcc executable path from command line, for example:
"\Program Files (x86)\VCC 2.1.0.8\vcc" vcc\Binfiles\bin\sig.bin (works for me} If that works you know your Vcc can launch a binary from the command line.

Manually changing file associations for Vcc versions can be difficult in windows. You have to remove the old associations first; this has burnt me many times. In regedit goto Computer\HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\ find .bin and delete the open with and user choice keys. You only have to remove keys that reference VCC. After the keys are removed you can then associate the 2.1.0.8 version of VCC

It is not a path issue and doing the .BIN file reassociation was one of the first things that I tried. As I mentioned in my original post, replacing the 2.1.0.8 version of the Vcc.exe, with the previous 2.1.0.7 Vcc.exe, completely removes the issue,

After further testing, this appears to be an 'intermittent' issue. I've tested both the .BIN double-click method and command line method of opening .BIN files - it is successful maybe 10% of the time, while 90% of the time VCC 2.1.0.8 will not launch.

This may be a local issue, but the 2.1.0.8 version of VCC is the first time I've encountered it on this system. It has worked flawlessly on 2.1.0.7, as well as previous releases of VCC.

My current system is Windows 11 22H2. I will try to test with other systems/versions, to rule out a local issue with this system.

Please tell us what .BIN files you are trying and any vcc errors in event viewer after vcc fails to launch so we can see if we can replicate.

I tested with a different box running Windows 10 version 1607 and have verified the same behavior as my Windows 11 box.

The .BIN file is incidental, with the issue being present in the several dozen .BIN files that I've tried. However, if you want a specific example, I just tested with DAGGORAT.BIN located on DAGGORAT.DSK image found on the Color Computer Archive here:

https://colorcomputerarchive.com/repo/Disks/Games/Dungeons%20of%20Daggorath%20%28Disk%20Patch%29%20%28Tandy%29.zip

Upon further testing, I've used Process Monitor from Sysinternals to verify that each time I attempt to open VCC 2.1.0.8 by double-clicking a .BIN file or by the command-line method of opening a .BIN file, the Vcc.exe process does start but closes quickly without displaying an application window.

In looking through the application logs in event viewer as you suggested, I am seeing the application crash errors each time the application fails to load.

Under Event ID: 1001 - the app crash errors report:

Fault bucket 1832871845682117734, type 1

There are also separate entries with Event ID: 1000 with the following information:

These event viewer log entries are also present on the Windows 10 box I tested as well.

I am now able to reproduce this. Looking into it.

There is a patched version that I think fixes this. Appreciate if you try it out and let me know how it does.
