Imagemagick Permission issue on windows server

[utbl]

Hi,

so we have a Microsoft Windows Server 2012 R2 Standard running. The server is used for a webapplication which uses imagemagick ffmpeg and another windows tool. The server / webapplication does not work all the time.
First I gave the imagemagick executables 777 permission, if the executables have 77 permission the webapplication works, but after a while the permission for those executables seems to change after if that happens the webapplication does not work anymore.

I already created a thread in the microsoft forum and one told me that I should also ask in the imagemagick forum.

Any idea what could case this and how to fix it, currently I always needs to change the permission on the server to 777 if I see that the webapplication does not work anymore.

Best regards

Well, that's a bug somewhere. IM doesn't change its own permissions. I suggest you track down what is changing those permissions.
