Carrara and Windows 11
I have a licensed copy of Carrara 8 running on a Windows 7 Pro computer. I would like to run Carrara on a Windows 11 Pro computer. However, the installer for Carrara 8 will not install Carrara in Windows 11. What do I need to do to run my copy of Carrara in Windows 11?

probably Carrara 8.5
I don't have Win 11 so cannot test if 8 works but the upgrade definitely does for other users
its frequently on sale if you are not in a hurry
run as administrator maybe...
install in a seperate folder and not in the Program Files folder
instal via DiM maybe... 8.1 was a free update if I recall correctly so you can download it from your account.
I run 8.1 no problems in Windows 11 Pro
or just copy all the Carrara folders from your Windows 7 and paste it into Windows 11 ... create a desktop shortcut and that should work.
Run install as admin. You have to put in the key. It definitely works. I am using win 11 pro. I have C8.5pro last ver as far as I can tell.
it was a paid update
I would strongly advise getting it to FlyGuy as so much added but as I said, frequently on sale
Oh maybe that is it. I did buy it on sale. So I would have a 64bit version. Try compatibility mode then. C7Pro also runs.
I run C8.5 Pro on Windows 11 at home. I installed it via the Daz DIM installer, not myself from zip files. There are occasional hiccups, but in generalit works. I am on my old laptop while on the road so can't test anything specific for you for Windows 11.
Carrara 7.2 pro installs fine on Win11, but I have a Huion tablet and so had to do the wintab32.dll workaround it get it to load.
If it matters, https://www.daz3d.com/forums/discussion/548131/carrara-crashes-with-huion-tablet-workaround#latest for ya. I installed to a folder outside of Program files though
Took the plunge and updated my oldest computer to Win 11. Not a clean install but opted for the update which allowed me to keep all my apps data etc. So far so good. Carrara 8.1 works as expected. Carrara 8.5 works, Octane for Carrara works but I had to sing in to my Octane acct. and it works. Hex works, and the bridge to daz. Zip and Rar files crash the explorer window. did some research, uninstalled CS4, zip rar files are now ok. DS4.10 and DS4.21 work.
Thanks fo the report. I am still running Win10 on a 12 core/24 thread AMD CPU with a middling nVidia GPU. Very fast Carrara frame renders (a few seconds) and wildly various DS iRay renders (minutes to hours). So ... the iRays become great backgrounds for fast animation foregrounds in Carrara.
I am thinking about a new machine with Win11, a fast AMD CPU and an nVidia 4090 card or similar which some say gives good iRay render times.
It's been a couple of months since my dive into widows 11. Overall impression?...to make a long story short, I reverted back to windows 10. All of my programs worked well enough, but getting to them was slow and sluggish. Navigation within the various programs was pretty good, but the day to day routine tasks within windows itself was a real test of patience. My system specs are really not that bad, 32gb ram, i7-4790K @ 4.00GHz, Windows 11 is probably pretty good on a modern PC with all the proper protocols, which my machine is lacking. Im back, up and running, on windows 10 and I'm content with that.
Windows 11 by default has the smart app control turned on when installed.. I found the same problem as you with very slow and sluggish starting of apps..
So, I turned it off and all is back to normal.
If you do turn it off you can only turn it back on again by reinstalling windows 11
Thanks for the feedback. So far I'm also still a Win10 user.
staying not straying
Windows 10 like Carrara is not broken, why mess with things
Not ruling out a new PC one day and latest OS but I wasn't even affected by the AWS outage because I don't web browse much, at least on PC, have an iPad for that and a smart TV for YouTube, which shows me heaps of ads
I only dislike the timing of them sometimes, with all the Ai you would think they wouldn't cut off commentry mid sentence.
** EDIT - UPDATE - Issue fixed as per post a few rows down. **
My carrara was getting along fine with Windows 11 until the most recent updates. A security feature that blocks add-ons and sub-routines is wreaking havoc on a variety of programs that I have, including Carrara 8.5 Pro. The Windows blocks seem random, but who knows. Here is the most recent obstruction when launching Carrara. Argh. Repeat, Carrara was working fine until recent Windows updates, and these issues are not only Carrara issues.
EDIT - in other programs, also getting error warning for Windows blocking python routines associated with add ons. Even blocked an attempt to update.
That's really bad news.
sorry Ted
I am keeping my Win 10
@Diomede
Sorry to hear. I seem to be up to date on w11 pro,(24H2) but not seeing this. I do not have smart app enabled. Might want to check defender settings and smart screen. However, this may help you out. I do keep updates paused though. Auto update is something I avoid.

Good news.
There was another Windows update (small one), which I assume was a patch of some sort. Without me doing anything for Carrara or Python-related files, I am no longer getting the errors. I guess they figured out they made a mistake and fixed it. Carrara is Carrara-ing again. Yay.
Thank you, Steve K, Wendy, and @3Deedlin for checking in on me.
EDIT - now I am not so sure an update fixed it. I am not getting the error, so it appears to be fixed, but the Windows 25H2 is appearing again as if it hasn't been updated. So I don't know. Carrara is working without error. Yay.
Though I never had any errors like you describe there have been several updates recently, in fact I'm updating now
again..... I thinks it's been 3 in the past week.
According to my update history, my most recent update was on October 15th. But I know there have been updates more recent than that. So it is a mystery to me what is going on with Windows 11. At least Carrara is loading without the error now.
That is better news.
mine have been on
13th Oct
19th Oct
20th and latest on the 26th Oct
So if you buy a new computer now, would you go with Win 10? If Carrara is shaky, I might be tempted using third party programs for malware protection. They have protected me well for years.
