Logitech QuickCam - Access Denied Error
For quite some time now I’ve been having problems in Windows XP Pro (using NTFS) by getting “Access is denied” error dialogs on accounts with limited access. After some time of research I was able to determine that the error was caused due to the Logitech QuickCam process called LVCOMSX.EXE. This process is initiated at login and reads/writes to a file called LVCOMSX.LOG. The reason for the error is because there is insufficient permissions set on the LVCOMSX.LOG file. To eliminate this error dialog at login, login with your Windows Administrator account and set permissions on the file C:\Windows\System32\LVCOMSX.LOG to the following (check each field), Modify, Read & Execute, Read, and Write. These permissions would either be set on the Users group or on specific users.
I’m not certain but to my knowledge the Logitech QuickCam process LVCOMSX.EXE is not a necessary process. However it is my understanding that if this process is not running you will loose some features of the Logitech QuickCam such as “Face Tracking”.

I’m glad to hear that this information was of use for you. I’m curious to know how you found this information/my web site?

Could you provide the steps to do this?
Is this in the control panel?
Thanks,

Hey Thanks!
This issue has been a nuisance for me and my guests (only the guest account was affected) for quite some time. I finally decided to track down the problem and found your site when I “Googled” it. Thanks again; you completly solved the problem.

Re: Lewis Lai
This information was not mentioned as it goes beyond the scope of this post. You have to use a Windows account that has Administrative privileges. You can see what each account has for privileges to a degree by going into your Control Panel -> User Accounts. Once you are using an account with that privilege you can then go about modifying the permissions on the LVCOMSX.LOG file by using Explore (Windows Key + E). The rest is really dependent on how your system is configure or how you wish to apply the permissions.

Re: C. Garrett
I’m happy that this material is easy to find and it resolved your problem. It’s quite an annoying one.

I just got the Logitech QuickCam Pro 4000 yesterday. First I tried it out with the Administrator account (no problem), and then with my regular account. Quite annoying to see the error message.
It seems that most software like this is not built with a business in mind. There is always some tweaking of installed files to make it work for everyone.
Thanks for the information!

Dear Helpdesk,
The furtest I get in my search is
C:\WINDOWS\SYSTEM32 LVCOMSX Notepad
I don’t find a log and I certainly do not find the log file with the fields; Modify, Read & Execute, Read, and Write., That the Warden is referring to?
Where can I grant those permission then?

Hi Anoir. So I’m not sure I’m following. You say that you found the LVCOMSX.LOG? If you can’t find the log use the search to locate the filename. If you did you just have to right click on the file and select properties then security to set the permissions. The directions on how to do this varies depending on if you are using Windows XP Pro or Windows XP Home.
Let me know either way.

I googled the following string and your site popped up first:
Quickcam Error Access Denied
Your solution works very well.
Thank you.

Thanks so much for this - it has been a pain for several family members with limited access for 6 months +!!!!
Glad it is now sorted out.

Your welcome. That’s what I’m hear for to help where I can. I hope to have more content similar to this soon.

Resolved in XP Home. While in an Administrators account, run cmd to open a dos command box, navigate to the LVCOMSX.LOG directory (windows\system32…) and use CACLS LVCOMSX.LOG command. This displays the permissions for the file. I then changed the BUILTIN\Users permissions from R (read) to F(full) using the command.
CACLS LVCOMSX.LOG /E /P BUILTIN\Users:F
Check after this that all is OK (CACLS LVCOMSX.LOG).
Worked for me anyway. Good Luck.
