Same problem here:
With XLS Padlock I need to wait almost 2 minutes for loading. Without XLS Padlock I just need to wait few seconds.
- I tested it with Excel 2010, 2013, 2016 and 365.
- I reinstalled MS Office several times.
- There are many customer who tested it and all of them need to wait so long time.
- I have a very good computer with AMD Ryzen 7 3700X 8-Core Processor 3,6 GHz, 16 GB, 64-Bit, Windows 10. So no bad hardware performance.
- During the loading time the file .EXE is in the task manager.
- I just use Windows Defender Antvirus.
- I saved my workbook into binary format. No difference.
- I deleted all graphics in my Workbook. No difference.
- I use XLS Padlock 2021.1
Maybe you can check some of these solutions. But I still wait for a solution.
