Reflector won't start anymore

[wifichicken]

Hello! I've been using your software for many months, and it's been perfect so far, but I recently installed a couple new backup drives and had an issue.

I created a new task to do a nightly backup to the new drives and since then, it looks like Reflector hasn't been able to start at all. There have been no backups created since I added the new task. If I run the Cobian Reflector Main Application, the icon comes up in the taskbar for a couple seconds and then disappears. If I'm quick, I can get the UI to open and see that the new task still doesn't have a calculated size. I've attached a screenshot.

In event viewer, I see the following Application Error:

Code: Select all

I've already tried running the Repair Permissions utility, deleting the AppData\Local\CobianSoft\Cobian Reflector directory, restarting the PC, uninstalling old .NET versions, and reinstalling Reflector.

Let me know if there's anything else I can provide to help diagnose! Thank you very much for any help

Update: I ran chkdsk on both new backup drives and found no issues

Look in the event viewer from an item from the .NET framwork.

Thanks for the quick reply!

I wasn't able to find anything in the event viewer with .NET as a source (at least within a relevant time frame).

I did find the following warning event logged under system at the same time as a crash:

Code: Select all

This security permission can be modified using the Component Services administrative tool.

Solved! The issue turned out to be caused by a folder with a blank name buried somewhere in the source directory. It was just called " ", a single space character. I have no idea how or why it was created.

I was able to access the UI after setting 'Calculate sizes' to False in the %localappdata%\\CobianSoft\Cobian Reflector\Cobian Reflector - UI Settings.ini file, then from there I used the process of elimination to find it. I selected one folder at a time to be the backup source until I found the one that crashed the program, then repeated for each subdirectory. Once I came across the problem folder, I was able to solve the issue by deleting it, but it gave me trouble. If anyone else encounters this issue, do not try to recycle it. Windows will just move it to the $RECYCLE.BIN folder at the top of the drive, which still prevents you from doing a full drive backup. It's also difficult to remove once it's inside the recycle bin. Explorer will refuse to empty the bin with it in there. I tried using rm -rf in git bash as well to empty the recycle bin and it threw permission errors. As I was trying to delete with cmd (unsuccesfully), it suddenly dissapeared. Very strange. If I could try again I would try to rename the folder before deleting it. Either way, it's all good now!
