SEN0524 - Cant download NAssistant 64bit

Hello,
I'm trying to change the protocol of the SEN0524 ToF sensor to i2c. Following the wiki I need to download NAssistant software, but I only receive a .crdownload file when downloading the 64bit version. When testing the 32 bit version I can start the program but it crashes when I press the recognize icon.
Thanks for the reply.
Disabling the firewall didn't help. Looking at the download link it seems to be a .crdownload file (https://dfimg.dfrobot.com/nobody/wiki/9d3ae205bc323a916241ad1ce41039ba.crdownload) unlike the 32bit version (https://dfimg.dfrobot.com/nobody/wiki/e829eee8c280ca89cb03c9b6701db2f4.zip) which is a .zip
Running as an adminstrator didn't help either. But I suspect the issue is running the 32bit version on an 64bit machine.

Sorry for the inconvenience. We have updated the download file.

Pls download the NAssistant 64bit again.
Thanks jenna, now everything works
Temporarily disable any antivirus or firewall software that might be interfering with the download or execution of the NAssistant software. Remember to re-enable them after completing the installation.
Run as administrator: Right-click on the NAssistant executable file and select "Run as administrator" to ensure that the software has the necessary privileges to make changes to your system.
