I get the below error while activating ChemDraw/ChemOffice: Generic communication error, “Error talking to server..... Generic communications error”


A firewall or proxy server in your Internet connection seems to be blocking the connection with the activation server. If that’s the case, the best option for you is to use the “Activate by uploading a file option” by following these steps:

1. Select the "Activate or deactivate by uploading a file" option and click on the "Activate" button. You will be prompted to save a local .BIN file to some location you choose (e.g., your Desktop). Then close the Activation Dialog. Continue installing the software to completion, if you haven't done so already.

2. Navigate to the following website: and log in. If you have never logged in, create an account using your organization’s email address. Once logged in, select "Devices>Upload Capability Request".

3. Select the "Choose File" option, navigate to your .BIN file and then select "Open". Then select "Send" to upload this .BIN file. The "Response.BIN" file is downloaded from the site to your computer.

4. The “Response.BIN” file should be placed in the folder C:\ProgramData\PerkinElmerInformatics\FNE\20.0 (for Windows) or /Users/Shared/com.perkinelmer.chemdraw.20.0/FNE (for Mac) on your hard drive. Then relaunch the software to activate the product.
