Hi,
Thanks for reaching out! We appreciate the opportunity to serve you.
A recent Windows update has made it so that the Wondermaps.exe can no longer detect Adobe Reader. We have a workaround but it will take a couple extra steps.
Enter this download code in our website: DWM3WZIS6YIDIPU
This will download a .zip folder instead of an .exe.
1) Move the .zip from your Downloads folder to your C: drive
2) Right click the .zip folder and then select Extract
3) After the extractor finishes running (you will need to click okay to give it permission to operate) you will have a .zip and a regular folder with the same name. Delete the .zip.
4) Open the file called StartHere.pdf in the new Wondermaps folder with Adobe Reader
I apologize for the inconvenience!
