ICO Plugin Error

[sarahl46199821]

I'm running into the above error whenever I attempt to export an ICO format file. I've been using the Telegraphics plugin for a few years with relatively minor issues. I last used this a few months ago to output icons, however I went to run a batch export of ICO files today and I get this error message before every export.

I have tried moving the file into both the Common folders for Adobe plugins as well as the individual program plugin folders. 

I have also tried to use it in PS 2020 (where I last used it without issue) and PS 2022 (downloaded to test if an update would work). 

I get the same result for all. I have also verified that I "unblocked" the file per the recommendation from another result here. 

Any feedback on what I might be doing wrong would be appreciated! The only thing that changed prior to today is that I ran CC updates that released for all of my installed apps. 

Thank you!

Telegraph has not updated their plugins since 2006.

The plugin has been running on borrowed time.

The documentation states:

Tested with:

• Photoshop all versions 3.0-7.0, CS, CS2 on PowerPC Macintosh (OS X, OS 9 and Classic)
• Photoshop 4.0 / MacOS 8.0 on 68K Macintosh
• Photoshop 5.0, 7.0 & CS on Windows 98/NT and XP.

The site also states to contact the developer with any issues or for updates: toby@telegraphics.com.au

You can start there and see if you get anywhere.

Thanks, I understand that it's very outdated. Unfortunately it seems to be the only plugin that exists to add ICO export functionality to Photoshop which I require, and was hoping someone else might have run into this and had a solution.

I use Irfan view to convert to .ico. It's been around for years and is a very robust little image editor with may plugins of its own. And of course, it's all free.
Pretty pathetic service Adobe's behalf. This has been requested for years and constantly treated with contempt.

Odd, I've had little issue with this plugin even in Photoshop 2024, but 2025 now renders it obsolete. Adobe... .ico is STILL used for favicons on web browsers... Edge/Chrome included. This is modern. Do your job and add .ico support. Not complicated.

Well, I"m tired of fighting with Adobe and I'm using the software from Adobe less and less as I learn other tools anyways. Update: I give up the fight. Let Adobe become obsolete. Here is a simple online converter tool. One extra step but meh.
