Install older version of Adobe product
We are looking for help with licenses for Adobe products we have purchased in recent years. These are primarily different and older versions of Adobe Photoshop, Acrobat Standard, Acrobat Pro, or Adobe Photoshop Elements. During several reinstallations, we found that the product could no longer be activated due to the shutdown of the activation server by Adobe. We get into a situation where we have a legally purchased product, but we are not able to operate it. We fear that over time, this situation will occur with other product versions. I would like to ask for a solution on how to proceed and legally put older Adobe products into operation. These are licenses, for example, from the TLP program.
