mistycoven: Try running the installer with administrator privileges. Confirm your antivirus/anti-malware isn't blocking the installer. Try changing the install location. You may also need to download the installer again if something got corrupted.

Braggadar: Did you burn the game directory, or the offline backup installers?

Sometimes it seems you're talking about the offline backups (.exe & .bin files) but sometimes it sounds a little like you've been backing up the game directory itself.

Be specific. What is the name of the "setup file" you're running to install your game?

neumi5694: 1. It would be much appreciated if you could NOT write the titles in capital letters.
You look like a spammer if you do so.

Man I ve been surfing the net since BBS years , I got say I'm a bit surprised that I still get the capital letter issue after 25 years .... Spammer ... lol .. ok ..

2. Are you sure you are not trying to actually uninstall the game or using an unofficial installer not provided by GOG?
As far as I am aware, all GOG installer require admin rights anyway (so there is no need to manually run them as admin) and do not rename the uninstall files.

When I click the file and accept the conditions for installing the game, I'm pretty sure I am installing the game, plus If the game ain't installed , I cannot really be un-installing the game . Yes I am installing the game .

"From Back up OFFLINE DRM" ... what does that even mean?
What is a offline DRM when you are talking about installers?

Braggadar: Did you burn the game directory, or the offline backup installers?

I burned the setup file only - only the game setup file from purchased games at GOG .

Sometimes it seems you're talking about the offline backups (.exe & .bin files) but sometimes it sounds a little like you've been backing up the game directory itself.

Yes the I've burned the = the offline backups (.exe & .bin files)

Be specific. What is the name of the "setup file" you're running to install your game?

randix: setup_close_combat_5_invasion_normandy_5.01a_hotfix_(19448)

randix: ... capital letters ...

randix: "From Back up OFFLINE DRM" ... what does that even mean? - Download game files only. Useful if you anticipate limited internet access, or want to have a backup. These installers don't support auto-updating, nor on-line features.

If you check on the Gog download page , some games only have one setup version of the setup files . In my case , I have 2 different types of setup files ( installation file ) ..

randix: " These installers don't support auto-updating, nor on-line features."

randix: But I have an install problem that happens when I run my game setup file. Ive included a snapshot of the error

" C:\GOG Games \CloseCombat 2\unins000.exe , An error has occurred while trying to rename a file in the destination directory MoveFile Failed; code 3221225501 "

How do I correctly install my games from files I drag from my dvd to my offline desktop , without being stuck with errors when instaloling . ?

AB2012: Assuming you're backing up the offline installers and not the folder of the installed game, (and make sure you have downloaded all the files available as larger games split them and you need all the parts), all I can think of is:-

1. Make sure you are using the correct file system when burning (ie, burn as UDF not ISO9660). UDF supports both long filenames and file sizes larger than 4GB. Pure ISO9660 does not without workaround extensions (Joliet).

2. Burning the files to optical also sets the "read-only" flag on the file system which may somehow be interfering with the install? Have you tried copying the installer files from optical to HDD, right-click on them in Explorer, Properties and unchecking "Read-Only" before running them?

3. Windows is somehow blocking it (try disabling Real-Time Defender, etc). Or if they "blocked" for being downloaded on another PC, right click, Properties, "Unblock"?

4. Make sure your Temporarily files folder isn't pointed to the optical drive letter (cannot write to a read-only disc).

I have a BD-R drive, and installing games directly from BD-R worked fine when I tested it.

neumi5694: I on the other hand am surprised that people still feel the urge to write in capital letters. That and your choice of words initially did let me believe this was just some bullshit randomly chosen from various reddit posts.

Sorry about that ... not intended to bother anyone ..neumi5694: Well, that's just it. "DRM" has nothing to do with the offline installers. That's something completely independent.
My Offline Installers directory contains something over 7 Terabyte.

There is a difference between old installers and new ones (you are using one of the new ones). The old installers were made before the Galaxy API was introduced, the new ones with a build number were built through the new API. Sometimes old games get a new installer when they get cloud support. In some cases however they never get updated. A few of those get that feature if you import them into Galaxy.neumi5694: Nope, that's not true. They install exactly the same as the installation through Galaxy.

I just copied and pasted what was on the download page , Again sorry not intended of challenging anyone's knowledge

I just name one example: Carcassonne.
You can play it offline of course, no matter if installed through Galaxy or through the offline installer.
But if you log in using the account of the developer, you get something extra. Again: no matter if you used the offline installer or Galaxy. That's DRM through an offline installer. Also several Multiplayer titles have online features when installed through the offline installer.

Anyway ... the (failed) attempt to rename files during the installation looks suspicious indeed. According to gogdb, you seem to use the newest version of the game, so we can exclude that as error source. The format of the CD should also not matter at all as long as the file can be read. If unsure, one can always copy it to the hard disc first before installing and run a check before the installation.

The failed attempt to rename a file either means that the file is not there in the first place or that it's locked, for the latter the culprit could be your antivirus solution.

When you try again, delete everything from the target directory that does not resemble "profile" or "save" (just in case you have some old savegames).

I burned the game setup file Only , no previous installation folders or files or saved games

Also disable your antivirus for a minute and make sure that Galaxy is not running (could be that Galaxy is accessing the file that very moment)

Gudadantza: Basically my guess is that your DVD reader is dying or the DVD disc sorta corrupted

randix: Also I would not believe it's the burner , since I ve tried 2 different burners and 2 different Dvds and dvd brands

neumi5694: Just for the sake of excluding the disk as error source for good ... could you try to redownload the installer and launch them from HD? The ones you mentioned should not be all too large.

Trooper1270: Have you set the burn rate (2x, 4x etc) in the software you are using to a level that your DVD burner and disc's are able to achieve ?.

Edit: Oh, and to be sure, you are burning your games as files on the disc (just like you would when copying to a hard disk) and not as disc images (iso's etc) ?.
