Dear l.s., I get an error while installing an extension. Failed to install the extension 'com.extract.chromakeyextract'. Please make sure the manifest.xml of this extension is valid and the extension manager recognises at least one product which the extension supports. What should I do? I have uninstalled all programs like Photoshop, Lightroom Extension Manager etc. Thank you in advance.
It worked with zxpinstaller :-)
