i finally got it to work. however it cant be used fully it says " contents fail to download" one of which is cutout which is the main thing i want to use it for. anywhay this is how it did it.
so when you get this error Payload\\PS Express.app\\Frameworks\\AdobeCreativeSDKAssetUX.framework\\AdobeCreativeSDKAssetUXResources.bundle\\PhotoBrowser.bundle\\PhotoBrowser.storyboardc\\AdobePhotoBrowserMoreToolbarButtonViewController.nib
it means you need to delete the "AdobePhotoBrowserMoreToolbarButtonViewController.nib" file. so open winrar(or any app you prefer. winrar is what i use) right click on the ipa file you downloaded and click view file and follow the directory till you see AdobePhotoBrowserMoreToolbarButtonViewController.nib and after you delete it you will still get error but with different .nib file. delete all the files that causes the error and youll be able to install the app with sideloadly.
P.S if the error says to delete object 12.3 file in a .nib file just delete the .nib file because if you delete the object 12.3 file later it will ask to delete file that i cant find, but if i delete the .nib file it works. this could be the reason why i get the contents fail to download after install but if i dont know other way to make it work. so if you find a better way please share 😉
