Not able to install ToadForOracle_Freeware_12.8.0.49_x64_En in windows 8.1 PC,
while installing Windows Installer error prompts,
“This installation package could not be opened. Contact the application vendor to verify that this is a valid Windows Installer package”,
I have tried to change the package properties to compatibility mode, but still prompts the same error
Could some one help me to resolve this issue.
