Update 2 - AutoCAD LT for Mac 2016 installation failure

[adamsjay]

Each time I open a session with AutoCAD LT for Mac 2016, a dialogue box prompt pops up telling me to download and install Update 2. Unfortunately, the installation fails each time. The error message says "The Installer encountered an error that caused the installation to fail. Contact the software manufacturer for assistance".

How do I resolve this issue?

Welcome to Autodesk Forums!

Hi,

You can find out more about the error in
/private/var/log/install.log file. It is rather big, you need to scroll to the end of the file and find strings about AutoCAD update.

You can also try to uninstall AutoCAD with "Remove AutoCAD" application, than install it again and try to apply the Update.

Welcome to the Autodesk Community!

If you go here you can download the updates and run them manually.

Looks like OP downloaded the Update successfully, and the error occurs during installation process.

Hi @maxim_k,

You might be right about that but I am not sure.

The logs should tell a lot!

Let's see how the OP responds.

Thanks as always.

John - I followed the link you provided, and downloaded Service Pack 2 again. Same issue - the installation failed. Do I really have to uninstall the program and reinstall? Pretty sure I just downloaded the program when I upgraded from AutoCAD LT for Mac 2013. How do I reinstall without a program disk?

[maxim_k]

You can download trial 2016 version installer and use it for installation.

Hi @adamsjay,

Before you do an uninstall and reinstall, lets try a Reset to see if that helps Reset is found under the AutoCAD pull down menu next to File.

You can obtain a new install either from a Trial of using the Virtual Agent

I did the Reset, but get the same installation failure.

HI @adamsjay,

I am sorry to hear that didn't help.  As Maxim_K suggests, a reinstall is the next step then.  I would also consider doing a complete uninstall first. (See AKN Article for details).

Please make sure that you also have full administrative rights for your user account.

I like to use the Virutal Agent to get my downloads as I submitted in my previous post.

Please post your results.

Thanks for the article about how to uninstall the program. I'll get back to you later about whether that fixes the issue. Right now, I'm on a project deadline and need to keep drawing.

Hi @adamsjay,

Did you change anything inside the AutoCAD LT 2016.app?

If no, are you using any disk clean tools to clean the disk? We have seen cases that some disk clean tools remove files aggressively and remove some files inside our product.

Thanks,
Wei

I have not modified the program at all. I do use MacKeeper to clean my computer. Perhaps this utility has removed an important AutoCAD file.

You shan't do it under any circumstances, because MacKeeper is well knowing "virus-like" software.

Here is the quote from this thread on Reddit:

"MacKeeper advertises itself as something that optimizes your Mac's speed and performance. It removes some expendable caches and sometimes it removes required system files while it's at it. Sometimes it removes iPhoto resource files and corrupts libraries. It's pretty much a massive scam targeted at people who don't know how to maintain their OS. 

The real evil and beauty is that the target audience wouldn't even know not to download it. They think they need a program like that when all they really need is to reboot, do a disk repair, or remove 3rd party launch agents and launch daemons.

To remove it:

Drag the app in /Applications into the trash. It will ask you to do a short survey about why you would be so brash as to delete such a useful tool. This is where you write the snarkiest comment you can think of. It should uninstall it's resource files too.

.....You have to trash the app and also anything with the word mackeeper or zeobit in the file name. There's usually a few files in these directories: 

~/library/launchagents /library/launchagents /library/launchdaemons

Also check:

~/library/preferences /library/preferences "

And I'm not sure that after removing MacKeeper and reinstalling AutoCAD you will be able to install Update 2. Further more there is a chance that you can not install AutoCAD again after removing it.

For now you can try to remove MacKeeper from your Mac, than try to install Update 2.

If it fails again - try to create new user account on your Mac (via Users and groups pane in Mac OS System preferences), login to this new account and try to install Update 2 from it. If this will help, you can return to you main user account and test AutoCAD. If everything is OK - remove new user account you created earlier.

But anyway - your System is now in unstable condition (after using MacKeeper on it). Maybe you even will have to fresh reinstall the whole system.

Wow! Thanks for the information. I will remove MacKeeper as you suggest, and try the next steps you recommend.

Hi @adamsjay,

I agree with Maxim about your add on.  Personally, if it were my Mac, I would format and reinstall the OS and apps.

You might be able to create a new user profile but I have done that on a couple of Macs in the same situation and have never been totally happy with the results.

Thanks to wei503, maxim_k and john.vellek for the useful advice. I removed Mackeeper and its files, removed & reloaded the OS and removed & reloaded the AutoCAD program and its files. Installation of Service Packs 1, 2 and 3 were successful. I appreciate everyone's help in solving this problem!
