NigelF 0 Report post Posted September 5, 2019 When you start Nitro Pro it starts as an icon on the task bar and a "normal" window fails to open. This is a new issue and until today Nitro Pro has been working fine. The winkey + left / right does not work. I have repair the installation, removed and reinstalled but no difference. Any other ideas ? Share this post Link to post Share on other sites
AllainU 0 Report post Posted September 5, 2019 Hello @NigelF, Thank you for reaching out to us through our Community Forums! Let us try some troubleshooting by referring to these steps: 1. Clear the content of the directory under C:\users\your_username\Appdata\local\temp. For whatever reason, not all temp files automatically remove themselves and is NOT usually caused by Nitro Pro files. 2. Download and run our Clean Up utility to uninstall your Nitro Pro: http://install.nitropdf.com/professional_12163574/install-cleanup/install-cleanup.zip NOTE: This clean-up tool will erase any existing signature files within Nitro so please save them to another location before using the clean-up tool in order to keep them. Please see this link for backing up custom stamps/signatures: https://kb.gonitro.com/knowledgebase#/search/stamps/000004307 3. Please clear all your downloads folder or delete all downloaded Nitro installers. This step is important because we noticed that if you are saving all the installers and you download them in the same folder (like the downloads folder), the EXE can pick up any MSI installer in that folder and you may pick-up one of the older builds instead of the newly downloaded package. 4. Download and install Nitro Pro 12.16 using below offline installers: x64-bit: http://install.nitropdf.com/professional_1108470/en/burn/nitro_pro11_ba_x64.msi x32-bit: http://install.nitropdf.com/professional_1108470/en/burn/nitro_pro11_ba_x86.msi If you are not sure which to pick, this will help: https://kb.gonitro.com/knowledgebase/#/search/64/000003790 5. After installation, you can activate by opening Nitro Pro, clicking on the Help tab > About Nitro Pro > Activate and entering your serial number. Thank you very much in advance and I am looking forward to hearing back from you. Share this post Link to post Share on other sites
