[Marcplaticolab]

every time i boot up illustrator i get this error, and all my setting are restored (including my actions which in a previous post i mentioned i cant restore from a save i have). what is wrong with illustrator CC 2015!

[Larry G. Schneider]

Sounds like your permissions are not set correctly.

[Marcplaticolab]

Hey larry thank you for responding, can you elaborate on that? what permissions are you talking about?

[Larry G. Schneider]

You need too make sure that AI has permission to read/write to the files in your user folders (either in Apps/Roaming on Windows or in Users/<yourname>/Library on Mac). They are hidden folders in most cases now.

Hello larry,

I get the exactly same errors.

How can i do the action you are talking about?

Can you post some step-by-step procedure?

Thanks

From a Google search try this

Illustrator Help | Setting preferences

I think I solved it.

When I installed Illustrator I chose to import settings from my other computer and that created a file called "Adobe Illustrator Prefs Cloud" or something like that.

I removed that file and Voila... At least It seem so for now.

[andre_venancio]

The same with me. Its the first time what this happend. I am user since Illustrator 7! The Adobe CC2015 for Windows have many bugs!

[Creventz]

I have the same issue.
Not every time I start it, but after a couple of hours of work this problem appears.

Normally Illustrator shows meassurements like this.

After a while working it starts formating figures like this:

If I resize anything after this problem occurs then Illustrator adds a space instead of a comma sign and the result is VERY VERY large things.

To fix it I have to restart Illustrator and then the corrupt preference file issue follows.

[Marcplaticolab]

yeah! i have that issue too, but i posted it separately. it is sooo annoying!

[berylkruger]

I have the same issue along with the corrupt preference file. I removed the preference file but two startups later it just gave me the error message again.

[Larry G. Schneider]

The you have some other software interfering. Try making a new user account any see if it works from there. Other causes can be browser add-ons esp in Chrome and to a lesser extent Firefox and Safari. Is your browser usually running at the same time? If so, try it with the browser off.

[berylkruger]

The issue seems to have resolved itself so far. I started Illustrator with a combination of various applications open, not open. Definitely not an issue if my browser is open. The first time I had the Corrupt Preference file issue was just after I updated to the latest version of Ai, and I opened a file via edit in Illustrator with Indesign. Will report back if it happens again.

[berylkruger]

Got the Preference file Corrupt message again. Programs open are Photoshop, Indesign, (both with files open) Creative Cloud, Chrome and Norton 360.

Maybe Doc Norton is a little too serious?

[Marcplaticolab]

i dont think its norton, in my case i dont even use an antivirus, and i still have this problem, i havent been able to get rid of it, so i har to revert back to 2014

[berylkruger]

Since updating I have not yet had the preference file corrupt issue, but tonight it once again happened when I opened an old .eps file. Computer had just been started, and only Muse and Photoshop was open. I also have an issue with moving selected points on a path by adding or subtracting numbers to the x and y value. It just moves the whole path.

[berylkruger]

Sooo... ran the latest update and the issue persists. Now I have the decimal issue back as well.

Use ". " and no "," and the problem will be solved for the time being. Re: Adobe Illustrator 2015 - Units-Bug

Exactly the same bug

[Tom_Van_Bortel]

Same problem here, corrupt preference file on startup and the number bug.

After removing the folder with settings (C:\Users\<user>\AppData\Roaming\Adobe\Adobe Illustrator 19 Settings) or a reinstall of Adobe Illustrator i still get the corrupt preference file.

Any suggestions?

[eszmum]

Same issue. Would be glad to find a solution. Deleting corrupt file didn't help.

[mr.henning]

Same problem here. After a while (not reproducable) Ai changes the meassurements and adding a factor of ~100 and 3-5 additional decimal digits to all values. After that you can't resize or even zoom because you get VERY high values. e.g. If you enter a zoom factor of 100% you will zoom in to 10000% but if you enter a zoom factor of  1% you will get 100%. VERY VERY STRANGE! After restart Ai you get the error message about a corrupt Prefs file.

Any help is welcome.

[Larry G. Schneider]

What happens if you hold down the Cmd(Ctrl)-Opt(Alt)-Shift keys when restarting your AI?

[Tom_Van_Bortel]

It then deletes the settings, but that doesn't help much, because after a while working with Adobe Illustrator the large numbers bug comes back (as described above)... and the settings are corrupt again.
