We recently got a new iMac Pro 5K 128GB, and set up Parallels Desktop for access to Windows apps used in our business. This is the first Win10 virtual machine we have set up (all previous deployments were Win7). We got things working so web links received in Outlook in Windows open in Safari on the Mac side (had to set it in Parallels options and in the default program for file types for .html in Win10 settings). We want PDF files received as attachments to open up in the full Acrobat program on the Mac (where we have Adobe CC 2018 Suite installed) rather than in Adobe Reader or Edge on Windows. When we go in the control panel and find the PDF extension, we can pop up the list of available apps, and can see "Adobe Acrobat (Mac)" and click on that. But then the setting Win10 displays says "ColorSync Utility (Mac)". We can't get it to hold "Adobe Acrobat (Mac)" as the setting. Any ideas?
