I have a system with windows 7 OS. I have one automation project which does the job of building the setup using NSIS wrapper. There are many file operations happens like copying and deleting the files etc. When the specific file is being deleted in visual
basic coding, I get the error like “Method 'DeleteFile' of object 'IFileSystem3' failed”. The file for this error coming is MDAC_TYP.EXE with size of 5 MB.
Scenario:
Server (Windows server 2012) drive is mapped to the local windows 7 system and whole operation is run in this mapped drive in client machine. Both the client and server are connected to the 1Gbps LAN. Now when I run my project to build the setup, it copies
all the application files to a folder called Temp and then it builds the setup exe using the NSIS (makeNSIS). After the creation of NSIS setup, it will delete all the source files from temp folder and again it will copy some other files to the same temp folder
for next setup.
Sometimes, while deleting the MDAC_TYP.exe file, I get the error as mentioned above. There are two folders with same structure called ‘Build1’ and ‘Build2’. Build1 is
used for testing environment and Build2 is for production environment. Temp folder will be created in both the folders while running testing and production setup.
The above said error comes for both the Build1 & Build2 folders and the
error comes occasionally (not every time) for the same exe. The MDAC_TYP.EXE file has read-only permission in the place from where I copy the file to the TEMP directory inside build1 & build2 for NSIS script. In the visual basic code, I use FileSystemObject.DeleteFile
method with force option set to true.
Once the error comes, I cannot rename/delete/move the file in any of the PC through UNC or even in server it cannot be deleted. If I try to rename/delete the file or its parent folder, the system from where I try to delete/rename gets hang. Even if we reboot
the client machine where the error was came for the operation, it does not solve the problem. Only the solution I found is to reboot my server. After rebooting the server, file can be renamed or deleted.
Other methods I tried are as below.
- Checked for file handle using process explorer in both client as well as server – No handles were found
- Checked Open files in the Shared folders of the server. - No open file connection found for the file.
- Tried rebooting the client machine – Not solved.
- Tried to delete/Rename the file using command in server – Not possible.
- Tried to delete/rename the file in server – No error and no message. Instead, server gets stuck.
- Checked for disk problems using chkdisk in server. No problems reported.
- Folder permission – The user ha full permission and there is no issue.
- Tried running the same build process after reboot – Everything works fine. But, again repeats after some time/day.
- Tried disconnecting the mapped drive at the time of error exists. But, still not able to rename.
- No antivirus/Event viewer log in both client as well as server.
Initially the error was coming in my windows XP PC. Now I upgraded to windows 7 (Fresh installation) and the error is still coming in new windows 7 machine.
Update:
I recently noticed that the same error also occurs when deleting the file msstdfmt.dll
Update 2:
I also got error for the ms word file, error is same. In all the 3 cases i found that there is only a common thing that is all 3 files has read-only attribute.
