I contacted Rob de Veij through his website contact page and he replied almost immediately. He simply asked if the working directory was correct, which made me realize that I had to run RVTools directly from C:\Program Files (x86)\Robware\RVTools\.exe rather than "C:\Program Files (x86)\Robware\RVTools\RVTools.exe"
Calling the program has definitely changed and below is the change I had to make in my batch file to accommodate that. I'm not sure if the next version will fix it, but I hope that helps you.
Original command with 4.2.2
for /f %%a in (%USERPROFILE%\Documents\VMware\RVTools\serverlist.csv) do "C:\Program Files (x86)\Robware\RVTools\RVTools.exe" -s %%a -c ExportAll2xlsx -u %ADMACCT%@domain.com -p %ADMPWD% -d %REPORTDIR% -f %%a.xlsX
New commands with 4.3.1
cd C:\Program Files (x86)\Robware\RVTools\
for /f %%a in (%USERPROFILE%\Documents\VMware\RVTools\serverlist.csv) do RVTools.exe -s %%a -c ExportAll2xlsx -u %ADMACCT%@domain.com -p %ADMPWD% -d %REPORTDIR% -f %%a.xlsx
