Hi Support.
DVD Shrink will not open unless I run it through Sandbox with no restrictions, then it opens. I also have Sandbox disabled since I read it does not work with XP x 64 Can you shed some light on this please.

Any ideas please.
Same here. Must be treated as a programs incompatibility 
I have pm’d the devs about XP 64 bit & sandbox virtualisation - whether this is still a problem. Will try them again.
You may wish to try clearing the sandbox entries for this file and rebooting. The file paths & keys are documented in an Intro to the Sandbox. Please ensure you know what you are doing if editing the registry (make a restore pt etc), and ensure you have no data in the sandbox before deleting files.
If you have installed into the sandbox by mistake, you will have to re-install, ensuring you get an elevated privs alert on running the installer. (Rename to installer to setup.exe of you do not).
Any one else any ideas re this problem from a D+ perspective?

I’m interested that you are running under XP 64 bit. Could you tell me was the sandbox enabled or disabled in V4 when you installed it? Was virtualisation enabled or disabled for manual sandboxing? That is, what was the default setting? Was any other indication given regarding limited support on XP 64bit?
Will help me with the FAQ if you can tell me.
Also did you find that sandbox virtualisation worked ok - that is at least as well as on any other OS? Or were there unusual issues?
Oh regarding your support issue, have you rebooted since you disbaled the sandbox - if not please try it!
Best wishes

DVD Shrink works fine on my system with the Sandbox disabled and D+ in Safe Mode.
Hi Mouse, sorry for the delay in answering. When I download V.4, Sanbox was enabled. The virtualization settings have never been touched so I assume they default to “off”. I have now put a tick in all the boxes (virtualization etc) and enabled Sanbox again, rebooted and DVD shrink still will not work until I run it through Sandbox (with no restrictions) Prior to this I had Sandbox disabled with the same result after rebooting. Incidently, I have “notify” me of replies ticked but I’m not getting any notifications, hence the delay in responding.
This seems very like the problem documented here. The post discusses different solutions.
To confirm try disabling guard32.dll as discussed in the topic.
I am interested in the fact that you can run the app manually sandboxed as ‘unrestricted’. Also ‘unvirtualised’? If so that is a good solution, and may be useful for others.

Hi Mouse.
Thanks for your reply and suggestion. I found guard32.dll in C/Windows/SysWow64 and I also found guard64.dll in C/Windows/system32 I could not find a way to disable it so I renamed the file and it’s working fine now. As soon as I rebooted I had a Comodo update notice. As I type I have not updated yet but I will do it now and get back to you if it changes things. Thank you for your help. John
I have now updated and it gave me the same version No. (4.0.141842.828) and reinstated guard32.dll which once again stops DVD Shrink from loading. It’s really not a problem because I can work around it, it’s just niggling.
John
The update is caused by the disablng of guard32/guard64. So best not to update, or you will have to rename again.
As said in the post I referenced, you can avoid the update prompt by disabling guardxx using systinternals autoruns. Please note the cautions about security effects of disbling guardxx and using autoruns in the post.

Thanks Mouse.
I found the entry in the autoruns but I will leave as is for the moment, as like you say, it could have other complications security wise.

I too have been having similar issue with DVD Shrink and running XP64 bit. It looks like it also was interfering with my DVD drive causing it to rip and burn very slowly to the point I replaced the drive. I was able to use and external drive, but that to seemed to run slower than normal. But after renaming the above files, it seemed to clean things up. I’ll have to try a burn, but reading has returned to normal and DVD Shrink will launch and right to ISO. Has any one had this issue on Windows 7?
I am going to move this to Bug reports, hope this is OK

If you have not done so already we would be grateful if you would post system details as described here.

Guard seems to be causing trouble to many. Why doesn’t comodo include a “deactivate guard permanently” feature like it does with D+?
