@Tom Strange, I can not see it in my list of apps.
I searched for the product
"Col", here I just find
ColorCop
I searched for the product
"CCA", here I get no results
I searched for the vendor
"Paciello", here I get no results
I searched for the vendor
"Trévisan", here I get no results
When I search for "Colour*.exe" then I get:
D:\PortableApps\PortableApps_ColorContrastAnalyzerPortable\Colour_Contrast_Analyser_3.0.1_Portable_x64.exe
D:\PortableApps\PortableApps_ColorContrastAnalyzerPortable\colour_contrast_analyser_32bit.exe
D:\PortableApps\PortableApps_ColorContrastAnalyzerPortable\Colour_Contrast_Analyser_64bit.exe
D:\PortableApps\PortableApps_ColorContrastAnalyzerPortable\Colour_Contrast_Analyser_3.1.1_Portable_x64.exe
D:\PortableApps\PortableApps_ColorContrastAnalyzerPortable\Colour_Contrast_Analyser_3.0.0_Portable_x64.exe
D:\PortableApps\PortableApps_ColorContrastAnalyzerPortable\Colour_Contrast_Analyser_3.1.2_Portable_x64.exe
Are the version numbers in the filenames the problem?
