Question

I accidentally deleted my Photoshop CC 1 application, how do I reinstall it?

Answer 1

There are advantages of using the direct download and installing over what is installed. It is the way I have been able to back out a buggy Adobe CC update.   You do not need to backup yous system first and remove all of Adobe's software and clean your system of residual Adobe rat droppings. Downloading is not part of the installation for you have downloaded.  You also now have your own copy of the install should you have problems in the future to re-install with.  When you do install your activation is still intact and all that you have added to Photoshop is still there and functional and does not need to be re-installed.  You do need to use menu Help>Updates to update CC for the install install CC version 14.0 The normal install will most likely do the same and need to be updated.  Don't know for sure I only installed CC that way the first time I installed CC.   The other two Installs I did were from the direct install.  One was to back out Adobe bad CC update.   You can also download all the CC updates and selectively install the ones you need. It took Adobe a month to fix their bad CC update.   The other install I had to do was to recover some CC file that became corrupt which caused some other CC update to fail to install.   After the re-install the update installed without a problem.  CC updates can be downloaded from All the Adobe CC Updates: The Direct Download Links for Windows | ProDesignTools
