Gives me an error of " Extension package is invalid. The extension will not be installed". I have tried it with several PS and DW extensions. I downloaded them all from the Adobe site so I have confidence in the extensions themselves. Is there a known bug and is there another way to install these?
maybe you know it already, but there is a difference between the extensions for the different Adobe programs. That's the reason why I have some of the E-managers saved in my Adobe directory (see screenshot):
which I use depending on the requirements. Here some links, you can use as an information:
http://www.adobe.com/exchange/em_download/ >>> Important note: MXP type extensions are not supported in Extension Manager CC. The MXP format has been replaced by the ZXP extension format. An MXP extension can be converted to a ZXP extension using the “Convert MXP Extension To ZXP” tool which can be found in the Tools menu in Extension Manager CS6.
