How To Install WebP Plugin for Photoshop CS5

[dodgeOrBURN]

Hello,

I need to reinstall the plugin (it mysteriously stopped working in February 2017) I do not see instructions for installing in either the copying or readme file that came with it. <http://telegraphics.com.au/sw/product/WebPFormat#webpformat>

I have pasted the WebPFormat64 file to

C:\Program Files\Adobe\Adobe Photoshop CS5 (64 Bit)\Plug-ins

C:\Program Files\Adobe\Adobe Photoshop CS5 (64 Bit)\Plug-ins\File Formats

C:\Program Files\Adobe\Adobe Photoshop CS5 (64 Bit)\Plug-ins\WebP

and restarted Photoshop each time but the image files still cannot be read. "Could not complete your request because it is not the right kind of document."

Please help me resolve this.

Thanks,

Lynda

What version of windows are you using?

If you go to File>Open you don't see it listed  (WebP) on the Format drop-down list?

[Jeff Arola]

I guess you unzipped (Extract) the

(right click and Extract All)

WebPFormat-1.2b4-win64.zip

and then opened the folder and copied the

WebPFormat64.8bi

to

C:\Program Files\Adobe\Adobe Photoshop CS5 (64 Bit)\Plug-ins

You might have to unblock the plugin

Right click on the WebPFormat64.8bi, click Properties and then check Unblock.

Then see if the plugin works in cs5.

Hello R_Kelly,

Thank you for your reply.

I am using Windows 10 Home Version 1703 (& Photoshop CS5)

I looked at properties and tried to unblock WebPFormat64.8bi and got this message:

Hit try again a few times and the security section disappeared.

Still not able to open webP files.

I would appreciate any further help you could suggest.

Thank you for your time and help.

Kindest regards,

Lynda

Try unblock the WebPFormat-1.2b4-win64.zip first, extract and then copy the plugin to the cs5 plugins folder.

I'd remove all the other WebP plugins in the cs5 plugins folder first.

Hello R_Kelly,

Thank you for your reply. I followed your instructions to unblock the zip prior to extracting and placed the file in

C:\Program Files\Adobe\Adobe Photoshop CS5 (64 Bit)\Plug-ins            with no success.

I also tried it in

C:\Program Files\Adobe\Adobe Photoshop CS5 (64 Bit)\Plug-ins\File Formats              and still get the message that the selected files could not be opened.

If you have any other suggestions, I would appreciate it.

Thank you very much for your time.

Kindest regards,

Lynda

In photoshop cs5 check in the File>Open dialog and see if on the Format drop-down WebP is listed.

Or in photoshop cs5 go to Help>About Plug-in and see in the WebP plugin is listed there.

Hello R_Kelly,

Thank you so much for your time. I really appreciate it.

I have checked those places and it was not listed.

Now I am even more confused. I looked at the version of Photoshop and it is

Adobe Photoshop Version: 12.0 (12.0x20100407 [20100407.r.1103 2010/04/07:14:00:00 cutoff; r branch]) x32

Operating System: Windows NT

Version: 6.2

My Windows is 10 Home Version 1703 x64

I just tried your steps with the 32 version of the webP plug-in and that didn't work either.

I just don't understand what happened because the plug in had worked prior to February 2017

Thank you for your time and help.

Kindest regards,

Lynda

Let's try resetting the photoshop cs5 preferences by deleting the cs5 preferences folder.

Go to C:\Users\User Nane\AppData\Roaming\Adobe

and delete the Adobe Photoshop CS5 folder

to see your AppData folder you need to enable showing of hidden files and folders as explained in the below link.
