Most of the time Capture One will not open due to the following:
Case 1
You are running an incompatible operating system, i.e. macOS 10.14.6 (Mojave) with Capture One 11.
The only options here are to upgrade to the latest version of Capture One or to downgrade your operating system.
See which OS versions are compatible with your version of Capture One here: Capture One system requirements and OS support
You can view your upgrade options by entering your license key here:
Case 2
The database you are trying to open is damaged or corrupt.
Open Capture One by holding down the Option (Mac) or Alt (Win) key, after initializing the application. This will prompt a window to appear on the screen, whereby you can choose to create a new database (Catalog or Session) or open a previously used, healthy database.
Case 3
The application is still running in the background.
- Windows: Use Ctrl + Alt + Delete to access the Task Manager and end any Capture One processes running in the background.
- Mac: Press Command + Option(Alt) + Esc and click on the corresponding application in the windows. Press Force Quit. Otherwise, right-click on the application's icon in the Dock and select Force Quit.
Case 4
OpenCL is failing to initialise and causing a crash.
See our help center articles on this issue here:
To disable OpenCL in Capture One in case of a crash on startup, follow the steps below:
- Windows: Run the script DONOT_useopencl.reg and restart Capture One (the download also contains a restore script to re-enable OpenCL useopencl.reg) - download here
- Mac: Download AdjustOpenCL_External.zip and run this application AdjustOpenCL_External.app, disable OpenCL, and restart Capture One.
Case 5 (for Windows users only)
The C++ libraries should be updated.
Install redistributable C++ 2015-2019 package from Microsoft available here.
Case 6 (Mac users only)
Capture One is not granted Full Disc access. This sometimes prevents OpenCL kernels from being built.
To allow Capture One to have full access to the computer, go to System Preferences and click on the Security & Privacy icon.
Then select Privacy at the top and Full Disc Access in the left pane.
Unlock the pane via the padlock icon at the bottom left. You will be prompted for your macOS user password.
Find Capture One on the list and checkmark it to allow full access. If it is not on the list, click on the +(plus) icon and locate Capture One in the Applications folder.

"Connection is invalid.
Capture One 20 got an error: Connection is invalid. (-609)"
Thank you and have a nice Sunday evening ;-)
I have checked the compatibility with my laptop, after installation, still cannot launch capture one 13.1.1.
Zenbook UX430UN, core i7 8th Gen U, RAM 16GB, MX150 Nvidia, 1080p, Windows 10 v1909.
I have tried above solutions, still cannot launch.
I have encountered this issue.
None of the above worked. After I've installed redistributable C++ 2015-2019 package from Miscrosoft the problem is gone.
Hi Mikhail,
Thank you for your comment.
Your suggestion was also added to this article.
We stuck in the "Capture One 21 got an error: Connection is invalid. (-609)" error (High Sierra)… and also the "AdjustOpenCL_External.app" freezes and hardly can complete its USELESS task!
What to do? Even the crash report can't be sent!
Nothing works. Can not open C1 21 with a catalog generated by C1 21 on Big Sur
I had Capture 22 15.4.19 installed on my windows 11 machine and it had been running fine until a couple days ago when I wanted to import a job and it would not load the program I got an error message saying I need to install .Net Runetme 6.0.1 and I download it and I nothing happend I could not get the program to load. So I uninstalled the Capture 22 15.4.19 and loaded 15.2.1.9 and it loaded up and ran fine. I contacted Victor at tech support and he sent me a .Net Runtime 6.0.8 file to install I did that and uninstalled the 15.2.19 and tried reinstalling the 15.4,19 and I got the same error message as before I'm really at my wits end and pulling the little bit of hair out of my head because I just brought a Nikon Z-9 and wanted to import the lossless raw files and can't untill I get the new update! Can someone please advise i really can't afford to loss anymore hair:-(
thanks,
Mel
Please help!
Just upgraded to Ventura 13.0.1 on a macbook M1 max with 64 mb. Capture one 22 keeps crashing. Holding Option and starting the app, and granting full access also crashes...
The application that supposedly disables OpenCL also does not work
Please see below.
I'm also having the same issue as Luis Sayo. I purchased the full license for Capture One 22 Pro and expect the software to work as long as I need it to. What is going on. Also, the support site layout is extremely unfriendly with respect to finding related issues or logging a complaint. I have current paying clients waiting on work. Need help ASAP - but I don't intend or need to upgrade to 23!!!

I had to go to my account page and selected download capture one:
When you arrive on the next screen to download, scroll down to get to the Download Previous Version:
The command prompts then direct you to the most recent update to Capture One 22. Reloading the app fixed the error. Hope this helps!!!
